Freeman Dyson's suggested approach to proving the Riemann Hypothesis using quasicrystals (from his 2009 AMS lecture)
T. AsselmeyerMaluga, "Braids, $3$manifolds, elementary particles: Number theory and symmetry in particle physics" (preprint 10/2019)
[abstract:] "In this paper, we will describe a topological model for elementary particles based on $3$manifolds. Here, we will use Thurston's geometrization theorem to get a simple picture: fermions as hyperbolic knot complements (a complement $C(K) = S^3âˆ–(K\times D^2)$ of a knot $K$ carrying a hyperbolic geometry) and bosons as torus bundles. In particular, hyperbolic $3$manifolds have a close connection to number theory (Bloch group, algebraic $K$theory, quaternionic trace fields), whichwill be used in the description of fermions. Here, we choose the description of $3$manifolds by branched covers. Every $3$manifold can be described by a $3$fold branched cover of $S^3$ branched along a knot. In case of knot complements, one will obtain a $3$fold branched cover of the $3$disk $D^3$ branched along a $3$braid or $3$braids describing fermions. The whole approach will uncover new symmetries as induced by quantum and discrete groups. Using the Drinfeld–Turaev quantization, we will also construct a quantization so that quantum states correspond to knots. Particle properties like the electric charge must be expressed by topology, and we will obtain the right spectrum of possible values. Finally, we will get a connection to recent models of Furey, Stoica and Gresnigt using octonionic and quaternionic algebras with relations to $3$braids (Bilson–Thompson model)."
V. K. Varma, S. Pilati and V. E. Kravtsov, "Conduction in quasiperiodic and quasirandom lattices: Fibonacci, Riemann, and Anderson models" (preprint 07/2016)
[abstract:] "We study the ground state conduction properties of noninteracting electrons in aperiodic but nonrandom onedimensional models with chiral symmetry, and make comparisons against Anderson models with nondeterministic disorder. The first model we consider is the Fibonacci lattice, which is a paradigmatic model of quasicrystals; the second is the Riemann lattice, which we define inspired by Dyson's proposal on the possible connection between the Riemann hypothesis and a suitably defined quasicrystal. Our analysis is based on Kohn's manyparticle localization tensor defined within the modern theory of the insulating state. In the Fibonacci quasicrystal, where all singleparticle eigenstates are critical (i.e., intermediate between ergodic and localized), the noninteracting electron gas is found to be a conductor at most electron densities, including the halffilled case; however, at various specific fillings $\rho$, including the values $\rho = 1/\rho^n$, where $g$ is the golden ratio and $n$ is any integer, the gas turns into an insulator due to spectral gaps. Metallic behaviour is found at halffilling in the Riemann lattice as well; however, in contrast to the Fibonacci quasicrystal, the Riemann lattice is generically an insulator due to singleparticle eigenstate localization, likely at all other fillings. Its behaviour turns out to be alike that of the offdiagonal Anderson model, albeit with different systemsize scaling of the bandcentre anomalies. The advantages of analysing the Kohn's localization tensor instead of other measures of localization familiar from the theory of Anderson insulators (such as the participation ratio or the Lyapunov exponent) are highlighted."
M. Lesiuk and B. Jeziorski, "Complete basis set extrapolation of electronic correlation energies using the Riemann zeta function" (preprint 05/2019)
[abstract:] "In this communication we present a method of complete basis set (CBS) extrapolation of correlation energies obtained with a systematic sequence of oneelectron basis sets. Instead of fitting the finitebasis results with a certain functional form, we perform analytic resummation of the missing contributions coming from higher angular momenta, $l$. The assumption that they vanish asymptotically as an inverse power of $l$ leads to an expression for the CBS limit given in terms of the Riemann zeta function. This result is turned into an extrapolation method that is very easy to use and requires no ``empirical'' parameters to be optimized. The performance of the proposed method is assessed by comparing the results with accurate reference data obtained with explicitly correlated theories and with results obtained with standard extrapolation schemes. On average, the errors of the zetafunction extrapolation are several times smaller compared with the conventional schemes employing the same number of points. A recipe for estimation of the residual extrapolation error is also proposed."

[excerpt:] "There is thus a possibility that the ancient dream of philosophers to connect all Nature with the properties of whole numbers will some day be realized. To do so physics will have to develop a long way to establish the details of how the correspondence is to be made. One hint for this development seems pretty obvious, namely, the study of whole numbers in modern mathematics is inextricably bound up with the theory of functions of a complex variable, which theory we have already seen has a good chance of forming the basis of the physics of the future. The working out of this idea would lead to a connection between atomic theory and cosmology."
D. Schumayer and D.A.W. Hutchinson, "Physics of the Riemann hypothesis", Rev. Mod. Phys. 83 (2011) 307–330
[abstract:] "Physicists become acquainted with special functions early in their studies. Consider our perennial model, the harmonic oscillator, for which we need Hermite functions, or the Laguerre functions in quantum mechanics. Here we choose a particular number theoretical function, the Riemann zeta function and examine its influence in the realm of physics and also how physics may be suggestive for the resolution of one of mathematics' most famous unconfirmed conjectures, the Riemann Hypothesis. Does physics hold an essential key to the solution for this more than hundredyearold problem? In this work we examine numerous models from different branches of physics, from classical mechanics to statistical physics, where this function plays an integral role. We also see how this function is related to quantum chaos and how its polestructure encodes when particles can undergo Bose–Einstein condensation at low temperature. Throughout these examinations we highlight how physics can perhaps shed light on the Riemann Hypothesis. Naturally, our aim could not be to be comprehensive, rather we focus on the major models and aim to give an informed starting point for the interested Reader."
M. Wolf, "Will a physicists prove the Riemann Hypothesis?" (preprint 10/2014)
[abstract:] "In the first part we present the number theoretical properties of the Riemann zeta function and formulate the Riemann Hypothesis. In the second part we review some physical problems related to this hypothesis: the links with random matrix theory, relation with the Lee–Yang theorem on the zeros of the partition function, random walks, billiards etc."
L. Ionescu, "Remarks on physics as number theory" (preprint 08/2011)
[abstract:] "There are numerous indications that physics, at its foundations, is algebraic number theory.
The Bohr model for the hydrogen atom is the starting point of a quantum computing model on serialparallel graphs is provided as the quantum system affording the partition function of the Riemann gas/primon model. The propagator of the corresponding discrete path integral formalism is a fermionic zeta value 'closely' related to the experimental value of the fine structure constant corresponding to the continuum path integral formalism of Feynman.
The duality of multiplicative number theory, as a theory of the graded Hopf module of integers, and the Kleinian geometry of the primary finite fields underlying its base of primitive elements, are briefly mentioned in this framework ('Integer CFT')."
I. GálvezCarrillo, R.M. Kaufmann and A. Tonks, "Three Hopf algebras from number theory, physics & topology, and their common background II: General categorical formulation" (preprint 01/2020)
[abstract:] "We consider three a priori totally different setups for Hopf algebras from number theory, mathematical physics and algebraic topology. These are the Hopf algebra of Goncharov for multiple zeta values, that of Connes–Kreimer for renormalization, and a Hopf algebra constructed by Baues to study double loop spaces. We show that these examples can be successively unified by considering simplicial objects, cooperads with multiplication and Feynman categories at the ultimate level. These considerations open the door to new constructions and reinterpretations of known constructions in a large common framework which is presented stepbystep with examples throughout. In this second part of two papers, we give the general categorical formulation."
A. LeClair, "An electrostatic depiction of the validity of the Riemann Hypothesis" (preprint 05/2013)
[abstract:] "We construct an electric field from the real and imaginary parts of an entire function $\xi(z)$ which arises in the quantum statistical mechanics of relativistic gases when the spatial dimension $d$ is analytically continued into the complex $z$ plane. This function is built from the Gamma and Riemann zeta functions and is known to satisfy the functional identity $\xi(z) = \xi(1z)$. We describe how this nontrivial identity can be demonstrated using quantum field theory arguments in a cylindrical geometry, where it relates finite temperature black body physics to the Casimir energy on a circle. The structure of the electric field in the critical strip is determined by its behavior near the Riemann zeros on the critical line $\Re(z) = 1/2$, where each zero can be assigned a plus or minus vorticity of a related pseudomagnetic field. Using these properties, we show that a hypothetical Riemann zero that is off the critical line leads to a frustration of the electric field, which is to say, an incompatibility with the electric field pattern that is a consequence of the infinite number of zeros along the critical line."
G. França and A. LeClair, "On the validity of the Euler product inside the critical strip" (preprint 10/2014)
[abstract:] "The Euler Product Formula relates Riemann's zeta function $\zeta(s)$ to an infinite product over primes, and is known to be valid for $\Re(s) > 1$. We provide arguments that the formula is actually valid for $\Re(s) > 1/2$ and $\Im(s)\neq 0$ due to the conditional convergence of the infinite product in this regime. The argument relies on four ingredients: the prime number theorem, an Abel transform, a central limit theorem for the Random Walk of the Primes series $\sum_p\cos(t\log p)$, where $p$ is a prime number, and the Cauchy criterion for convergence. The significance of $\Re(s) > 1/2$ arises from the universality of the $N^{1/2}$ growth of fluctuations in various central limit theorems for independent and weakly dependent random processes, which are common in statistical physics for systems of size $N$. Numerical evidence of this surprising result is presented, and some of its consequences are discussed."
K.R. Willison, "An intracellular calcium frequency code model extended to the Riemann zeta function" (preprint 05/2019, submitted to arXiv.org)
[abstract:] "We have used the Nernst chemical potential treatment to couple the time domains of sodium and calcium ion channel opening and closing rates to the spatial domain of the diffusing waves of the travelling calcium ions inside single cells. The model is plausibly evolvable with respect to the origins of the molecular components and the scaling of the system from simple cells to neurons. The mixed chemical potentials are calculated by summing the concentrations or particle numbers of the two constituent ions which are pure numbers and thus dimensionless. Chemical potentials are true thermodynamic free Gibbs/Fermi energies and the forces acting on chemical flows are calculated from the natural logarithms of the particle numbers or their con centrations. The mixed chemical potential is converted to the time domain of an action poten tial by assuming that the injection of calcium ions accelerates depolarization in direct proportion to the amplitude of the total charge contribution of the calcium pulse. We assert that the natural logarithm of the real component ($\zeta_n$) of the imaginary term ($\zeta_n i$) of any Riemann zeta zero ($1â„2+\zeta_n i$) corresponds to an instantaneous calcium potential ($Z_n$). In principle, in a physiologically plausible fashion, the first few thousand Riemann $\zeta$zeros can be encoded on this chemical scale manifested as regulated stepchanges in the amplitudes of naturally occurring calcium current transients. We show that pairs of $Z_n$ channels can form Dirac fences which encode the logarithmic spacings and summed amplitudes of any pair of Riemann zeros. Remarkably the beat frequencies of the pairings of the early frequency terms ($Z_nZ_{n+1}$, $Z_nZ_{n+2},\dots$) overlap the naturally occurring frequency modes ($\gamma,\delta,\theta$) in vertebrate brains. Action potential control of calcium transients is a process whereby neuronal systems construct precise step functions; actually Dirac distributions which also underpin the Riemann mathematics. The equation for the time domain in the biological model has a similar form to the Riemann zeta function on the halfplane and mimics analytical continuation on the complex plane. Once coupled to neurophysiological binding processes these transients may underpin calculation in eukaryotic nervous systems."
V. Blomer, J. Bourgain and Z. Rudnick, "Small gaps in the spectrum of the rectangular billiard" (preprint 04/2016)
"We study the size of the minimal gap between the first $N$ eigenvalues of the Laplacian on a rectangular billiard having irrational squared aspect ratio $\alpha$, in comparison to the corresponding quantity for a Poissonian sequence. If $\alpha$ is a quadratic irrationality of certain type, such as the square root of a rational number, we show that the minimal gap is roughly of size $1/N$, which is essentially consistent with Poisson statistics. We also give related results for a set of $\alpha$'s of full measure. However, on a fine scale we show that Poisson statistics is violated for all $\alpha$. The proofs use a variety of ideas of an arithmetical nature, involving Diophantine approximation, the theory of continued fractions, and results in analytic number theory. One of our results is conditional on the Riemann Hypothesis."
J. Mayoh and A.M. GarcíaGarcía, "Number theory, periodic orbits and superconductivity in nanocubes" (preprint 04/2014)
[abstract:] "We combine mean field, number theory and semiclassical techniques to study superconductivity in isolated superconducting nanocubes and nanosquares of size $L$ in the limit. We study the case in which disorder is negligible and $k_FL\gg 1 where $k_F$ is the Fermi wave vector. By using periodic orbit theory we find an explicit analytical expression of the size dependence of the superconducting order parameter that takes into account contributions from both the spectral density and the matrix elements related to density fluctuations of the onebody eigenstates. We employ number theory techniques to compute analytically the average size dependence of the matrix elements. The leading size dependence of the matrix elements seems to be universal as it agrees with that found in chaotic grains. For sizes $L \gtrsim 10$nm there is very good agreement between numerical and analytical results. For the parameters that describe conventional metallic superconductors deviations from the bulk limit are still important for grains as large as $L\sim 50$nm."
J. Peng, S. Sun, V.K. Narayana, V.J. Sorger and T. ElGhazawi, Integrated nanophotonics architecture for residue number system arithmetic" (preprint 11/2017)
[abstract:] "Residue number system (RNS) enables dimensionality reduction of an arithmetic problem by representing a large number as a set of smaller integers, where the number is decomposed by prime number factorization using the moduli as basic functions. These reduced problem sets can then be processed independently and in parallel, thus improving computational efficiency and speed. Here we show an optical RNS hardware representation based on integrated nanophotonics. The digitwise shifting in RNS arithmetic is expressed as spatial routing of an optical signal in $2\times 2$ hybrid photonicplasmonic switches. Here the residue is represented by spatially shifting the input waveguides relative to the routers outputs, where the moduli are represented by the number of waveguides. By cascading the photonic $2\times 2$ switches, we design a photonic RNS adder and a multiplier forming an alltoall sparse directional network. The advantage of this photonic arithmetic processor is the short (10's ps) computational execution time given by the optical propagation delay through the integrated nanophotonic router. Furthermore, we show how photonic processing inthenetwork leverages the natural parallelism of optics such as wavelengthdivisionmultiplexing or optical angular momentum in this RNS processor. A key application for photonic RNS is the functional analysis convolution with widespread usage in numerical linear algebra, computer vision, language image and signal processing, and neural networks."
G. França and A. LeClair, "Statistical and other properties of Riemann zeros based on an explicit formula for the $n$th zero" (preprint 07/2013)
[abstract:] "Very recently, a transcendental equation satisfied by the $n$th Riemann zero on the critical line was derived by one of us. Here we provide a more detailed analysis of this result, demonstrating more rigorously that the Riemann zeros occur on the critical line with real part equal to 1/2, and their imaginary parts satisfy such a transcendental equation. From this equation, the counting of zeros on the critical line can be derived, yielding precisely the Riemann–von Mangoldt counting function $N(T)$ for the zeros on the entire critical strip. Therefore, these results constitute a proposal for establishing the validity of the Riemann Hypothesis. We also obtain an approximate solution of the transcendental equation, in closed form, based on the Lambert $W$ function. This yields a very good estimate for the Riemann zeros, for arbitrarily high values on the critical line. We then obtain numerical solutions of the complete transcendental equation, yielding accurate numbers for the Riemann zeros, which agree with previous known results found in the literature. Employing these numerical solutions, we verify that they are accurate enough to confirm Montgomery's pair correlation conjecture and also to reconstruct the prime number counting formula."
A. Dixit and A. Roy, "Analogue of a Focktype integral arising from electromagnetism and its applications in number theory" (preprint 07/2019)
"Closedform evaluations of certain integrals of $J_{0}(\xi)$, the Bessel
function of the first kind, have been crucial in the studies on the
electromagnetic field of alternating current in a circuit with two groundings, as can be seen from the works of Fock and Bursian, Schermann etc. Koshliakov's generalization of one such integral, which contains $J_s(\xi)$ in the integrand, encompasses several important integrals in the literature including Sonine's integral. Here we derive an analogous integral identity where $J_{s}(\xi)$ is replaced by a kernel consisting of a combination of
$J_{s}(\xi)$, $K_{s}(\xi)$ and $Y_{s}(\xi)$ that is of utmost importance in
number theory. Using this identity and the Voronoi summation formula, we derive a general transformation relating infinite series of products of Bessel functions $I_{\lambda}(\xi)$ and $K_{\lambda}(\xi)$ with those involving the Gaussian hypergeometric function. As applications of this transformation, several important results are derived, including what we believe to be a corrected version of the first identity found on page $336$ of Ramanujan's Lost Notebook."

[abstract:] "In this paper, we investigate the plasmonic nearfield localization and the farfield scattering properties of nonperiodic arrays of Ag nanoparticles generated by prime number sequences in two spatial dimensions. In particular, we demonstrate that the engineering of plasmonic arrays with large spectral flatness and particle density is necessary to achieve a high density of electromagnetic hot spots over a broader frequency range and a larger area compared to strongly coupled periodic and quasiperiodic structures. Finally, we study the farfield scattering properties of prime number arrays illuminated by plane waves and we discuss their angular scattering properties. The study of prime number arrays of metal nanoparticles provides a novel strategy to achieve broadband enhancement and localization of plasmonic fields for the engineering of nanoscale nanoantenna arrays and active plasmonic structures."

[abstract:] "Many natural patterns and shapes, such as meandering coastlines, clouds, or turbulent flows, exhibit a characteristic complexity mathematically described by fractal geometry. In recent years, the engineering of selfsimilar structures in photonics and nanooptics technology enabled the manipulation of light states beyond periodic or disordered systems, adding novel functionalities to complex optical media with applications to nanodevices and metamaterials. Here, we extend the reach of fractal 'photonics' by experimentally demonstrating multifractality of light in engineered arrays of dielectric nanoparticles. Our findings stimulate fundamental questions on the nature of transport and localization of wave excitations with multiscale fluctuations beyond what is possible in traditional fractal systems. Moreover, our approach establishes structureproperty relationships that can readily be transferred to planar semiconductor electronics and to artificial atomic lattices, enabling the exploration of novel quantum phases and manybody effects that emerge directly from fundamental structures of algebraic number theory."

P. Rosakis, "Continuum Surface Energy from a Lattice Model" (preprint 01/2012)
[abstract:] "The energy of a homogeneously deformed, faceted crystal is calculated in the context of a central force lattice model in two dimensions. It is shown that the energy equals the bulk elastic energy, plus the integral over the boundary of a surface energy density, plus the sum over the vertices of a corner energy function. This is an exact result when the interatomic potential has finite range; for an infiniterange potential it is asymptotically valid as the lattice parameter tends to zero. The surface energy density is obtained explicitly as a function of the deformation gradient and boundary normal. The corner energy is found as an explicit function of the deformation gradient and the normals of the two facets meeting at the corner. A new bond counting approach is used, which allows the problem to be reduced to the well known lattice point problem of number theory."
S. Matsutani, "A novel discrete theory of a screw dislocation in the BCC crystal lattice" (preprint 06/2019)
[abstract:] "In this paper, we proposed a novel method using the elementary number theory to investigate the discrete nature of the screw dislocations in crystal lattices, simple cubic (SC) lattice and body centered cubic (BCC) lattice, by developing the algebraic description of the dislocations in the previous report (Hamada, Matsutani, Nakagawa, Saeki, Uesaka, Pacific J. Math. for Industry 10 (2018), 3). Using the method, we showed that the stress energy of the screw dislocations in the BCC lattice and the SC lattice are naturally described; the energy of the BCC lattice was expressed by the truncated Epstein–Hurwitz zeta function of the Eisenstein integers, whereas that of SC lattice is associated with the truncated Epstein–Hurwitz zeta function of the Gauss integers."

[abstract:] "Synchronization in networks with delayed coupling are ubiquitous in nature and play a key role in almost all fields of science including physics, biology, ecology, climatology and sociology. In general, the published works on network synchronization are based on data analysis and simulations, with little experimental verification. Here we develop and experimentally demonstrate various multicluster phase synchronization scenarios within coupled laser networks. Synchronization is controlled by the network connectivity in accordance to number theory, whereby the number of synchronized clusters equals the greatest common divisor of network loops. This dependence enables remote switching mechanisms to control the optical phase coherence among distant lasers by local network connectivity adjustments. Our results serve as a benchmark for a broad range of coupled oscillators in science and technology, and offer feasible routes to achieve multiuser secure protocols in communication networks and parallel distribution of versatile complex combinatorial tasks in optical computers."
L.F. Alday and J.B. Bae, "Rademacher expansions and the spectrum of 2d CFT" (preprint 12/2019)
[abstract:] "A classical result from analytic number theory by Rademacher gives an exact formula for the Fourier coefficients of modular forms of nonpositive weight. We apply similar techniques to study the spectrum of twodimensional unitary conformal field theories, with no extended chiral algebra and $c > 1$. By exploiting the full modular constraints of the partition function we propose an expression for the spectral density in terms of the light spectrum of the theory. The expression is given in terms of a Rademacher expansion, which converges for spin $j \neq 0$. For a finite number of light operators the expression agrees with a variant of the Poincare construction developed by Maloney, Witten and Keller. With this framework we study the presence of negative density of states in the partition function dual to pure gravity, and propose a scenario to cure this negativity."
L. Dal Negro, Y. Chen and F. Sgrignuoli, "Aperiodic photonics of elliptic curves" (preprint 12/2019)
[abstract:] "In this paper we propose a novel approach to aperiodic order in optical science and technology that leverages the intrinsic structural complexity of certain nonpolynomial (hard) problems in number theory and cryptography for the engineering of optical media with novel transport and wave localization properties. In particular, we address structureproperty relationships in a large number (900) of light scattering systems that physically manifest the distinctive aperiodic order of elliptic curves and the associated discrete logarithm problem over finite fields. Besides defining an extremely rich subject with profound connections to diverse mathematical areas, elliptic curves offer unprecedented opportunities to engineer light scattering phenomena in aperiodic environments beyond the limitations of traditional random media. Our theoretical analysis combines the interdisciplinary methods of point patterns spatial statistics with the rigorous Green's matrix solution of the multiple wave scattering problem for electric and magnetic dipoles and provides access to the spectral and light scattering properties of novel deterministic aperiodic structures with enhanced lightmatter coupling for nanophotonics and metamaterials applications to imaging and spectroscopy."

[abstract:] "In this paper, we show that the linear dielectrics and magnetic materials in matter obey a special kind of mathematical property known as Cesàro convergence. Then, we also show that the analytical continuation of the linear permittivity and permeability to a complex plane in terms of Riemann zeta function. The metamaterials are fabricated materials with a negative refractive index. These materials, in turn, depend on permittivity and permeability of the linear dielectrics and magnetic materials. Therefore, the Cesàro convergence property of the linear dielectrics and magnetic materials may be used to fabricate the metamaterials."

[abstract:] "We consider $N$ point vortices $s_j$ of strengths $\kappa_j$ moving on a closed (compact, boundaryless, orientable) surface $S$ with riemannian metric $g$. As far as we know, only the sphere or surfaces of revolution, the latter qualitatively, have been treated in the available literature. The aim of this note is to present an intrinsic geometric formulation for the general case. We give a simple proof of Kimura's conjecture that a dipole describes geodesic motion. Searching for integrable vortex pairs systems on Liouville surfaces is in order. The vortex pair system on a triaxial ellipsoid extends Jacobi's geodesics. Is it Arnold–Liouville integrable? Not in our wildest dreams is another possibility: that quantizing a vortex system could relate with a million dollars worth question, but we took courage – nerve is more like it – to also present it."

[abstract:] "BogomolnyLeyvrazSchmit (1996) and Peter (2002) proposed an asymptotic formula for the correlation of the multiplicities in length spectrum on the modular surface, and Lukianov (2007) extended its asymptotic formula to the Riemann surfaces derived from the congruence subgroup $\Gam_0(n)$ and the quaternion type cocompact arithmetic groups. The coefficients of the leading terms in these asymptotic formulas are described in terms of Euler products over prime numbers, and they appear in eigenvalue statistic formulas found by Rudnick (2005) and Lukianov (2007) for the LaplaceBeltrami operators on the corresponding Riemann surfaces. In the present paper, we further extend their asymptotic formulas to the higher level correlations of the multiplicities for any congruence subgroup of the modular group."
R. Movassagh, Y. Tsuji and R. Hoffmann, "The exact form of the Green's function of the Hückel (tight binding) model" (preprint 07/2014)
[abstract:] "The applications of the Hückel (tight binding) model are ubiquitous in quantum chemistry and solid state physics. The matrix representation is isomorphic to an unoriented vertex adjacency matrix of a bipartite graph, which is also the Laplacian matrix plus twice the identity. In this paper, we analytically calculate the determinant and, when it exists, the inverse of this matrix in connection with the Green's function, $G$, of the $N \times N$ Hückel matrix for linear chains and cyclic systems. For an open linear chain we prove that $G$ is a real symmetric matrix whose entries are $G(r,s) = (1)^{\frac{r+s1}{2}}$ when $r$ is even and $s < r$ is odd; $G(r,s)=0$ otherwise. A corollary is a closed form expression for a Harmonic sum. For a ring we calculate the inverse, give formulas for the entries and find that it is always a Toeplitz matrix. We then extend the results to $d$dimensional lattices, whose linear size is $N$. The existence of the inverse becomes a question of number theory. We prove that the inverse exists if and only if $N+1$ and $d$ are odd and $d$ is smaller than the smallest divisor of $N+1$. We corroborate our results by numerical demonstrations of the entry patterns of the Green's function and discuss applications related to transport and conductivity."

"In addition to the practical advances required for this result, the answer also has theoretical implications.

K. Nakayama, F. Takahashi and T.T. Yanagida, "Number theory dark matter" (preprint 02/2011)
[abstract:] "We propose that the stability of dark matter is ensured by a discrete subgroup of the U(1)BL gauge symmetry, Z_2(BL). We introduce a set of chiral fermions charged under the U(1)BL in addition to the righthanded neutrinos, and require the anomalycancellation conditions associated with the U(1)BL gauge symmetry. We find that the possible number of fermions and their charges are tightly constrained, and that nontrivial solutions appear when at least five additional chiral fermions are introduced. The Fermat theorem in the number theory plays an important role in this argument. Focusing on one of the solutions, we show that there is indeed a good candidate for dark matter, whose stability is guaranteed by Z_2(BL)."
Bo Hu, "Neutrino mixing and discrete symmetries" (preprint 12/2012)
[abstract:] "A model independent study of neutrino mixing based on a new method to derive mixing patterns is presented. An interesting result we find is that, in the case where unbroken residual symmetries of the Majorana neutrino and lefthanded chargedlepton mass matrices obey some general assumptions, the complete set of possible mixing patterns can be determined by the solutions to the constraint equation with the help of algebraic number theory. This method can also be applied to more general cases beyond the minimal scenario. Several applications and phenomenological implications are discussed."

It also seeks to provide an experimental basis to discover some of the mathematical enigmas surrounding these conjectures, by providing Matlab and C programs which the reader can use to explore and better understand these systems."
C. Moore and A. Russell, "Approximate representations and approximate homomorphisms" (preprint 09/2010)
[abstract:] "Approximate algebraic structures play a defining role in arithmetic combinatorics and have found remarkable applications to basic questions in number theory and pseudorandomness. Here we study approximate representations of finite groups: functions f:G > U_d such that Pr[f(xy) = f(x) f(y)] is large, or more generally Exp_{x,y} f(xy)  f(x)f(y)^2 is small, where x and y are uniformly random elements of the group G and U_d denotes the unitary group of degree d. We bound these quantities in terms of the ratio d / d_min where d_min is the dimension of the smallest nontrivial representation of G. As an application, we bound the extent to which a function f : G > H can be an approximate homomorphism where H is another finite group. We show that if H's representations are significantly smaller than G's, no such f can be much more homomorphic than a random function.
We interpret these results as showing that if G is quasirandom, that is, if d_min is large, then G cannot be embedded in a small number of dimensions, or in a lessquasirandom group, without significant distortion of G's multiplicative structure. We also prove that our bounds are tight by showing that minors of genuine representations and their polar decompositions are essentially optimal approximate representations."
B. Luque, O. Miramontes and L. Lacasa, "Number theoretic example of scalefree topology inducing selforganized criticality", Phys. Rev. Lett. 101 (2008) 158702
[abstract:] "In this Letter we present a general mechanism by which simple dynamics running on networks become selforganized critical for scalefree topologies. We illustrate this mechanism with a simple arithmetic model of division between integers, the division model. This is the simplest selforganized critical model advanced so far, and in this sense it may help to elucidate the mechanism of selforganization to criticality. Its simplicity allows analytical tractability, characterizing several scaling relations. Furthermore, its mathematical nature brings about interesting connections between statistical physics and number theoretical concepts. We show how this model can be understood as a selforganized stochastic process embedded on a network, where the onset of criticality is induced by the topology."
D. Vilone, "Complex network approach to number theory" (preprint 09/2014)
[abstract:] "In this short paper, following the most recent advances in complex network theory, a new approach to number theory with potential applications to other fields is proposed. The model by GarciaPerez, Serrano and Boguna, introduces an algorithm which allows to create a bipartite graph of integers (with primes and composites) statistically very close to the real one. Since the algorithm is defined a priori, we can have a description of the simulated prime number distribution in terms of a known differential equation, which in general can be treated more easily. The so determined properties of the simulated distribution can give useful hints about the behavior of the real prime number distribution. In principle it could be also possible to demonstrate open questions in number theory, proven the total equivalence of the simulated and real distributions. I show that the model by GarciaPerez, Serrano and Boguna, though very good to describe the architecture of the relations among composites and primes, can not be useful to catch the most subtle properties of prime numbers. Anyway, the path suggested by such model is very promising, and should drive researchers to look for more refined algorithms to simulate the structure of integer numbers."

applied to the glassy systems and neural networks" (presented at International Conference on Theoretical Physics, Paris, 22–27 July 2002)
[Abstract:] "In the present paper it is described how the Riemann zeta function could be a very useful tool
in the analyze of the glassy systems and the neural networks. According to A. Crisanti and F. Ritort, this kind of
complex systems could be analyzed using a simple solvable model of glass: "The oscillator model" which is
defined by a set of N noninteracting harmonic oscillators with energy. The Riemann zeta function is
used to describe the CrisantiRitort System. It has been also made a topological study in order to have a more
intuitive representation of the critical points, where the states of the system changes."
P. Le Doussal, Z. Ristivojevic and K.J. Wiese, "Exact form of the exponential correlation function in the glassy superrough phase" (preprint 04/2013)
[abstract:] "We consider the randomphase sineGordon model in two dimensions. It describes twodimensional elastic systems with random periodic disorder, such as pinned fluxline arrays, random field XY models, and surfaces of disordered crystals. The model exhibits a superrough glass phase at low temperature $T < T_{c}$ with relative displacements growing with distance $r$ as $\bar{\langle [\theta(r)\theta(0)]^2\rangle} \simeq A(\tau) \ln^2 (r/a)$, where $A(\tau) = 2 \tau^2 2 \tau^3 +\mathcal{O}(\tau^4)$ near the transition and $\tau=1T/T_{c}$. We calculate all higher cumulants and show that they grow as $\bar{\langle[\theta(r)\theta(0)]^{2n}\rangle}_c \simeq [2 (1)^{n+1} (2n)! \zeta(2n1) \tau^2 + \mathcal{O}(\tau^3) ] \ln(r/a)$, $n \geq 2$, where $\zeta$ is the Riemann zeta function. By summation we obtain the decay of the exponential correlation function as $\bar{\langle e^{iq\left[\theta(r)\theta(0)\right]}\rangle} \simeq (a/r)^{\eta(q)} \exp(\frac{1}{2}\mathcal{A}(q)\ln^2 (r/a))$ where $\eta(q)$ and ${\cal A}(q)$ are obtained for arbitrary $q \leq 1$ to leading order in $\tau$. The anomalous exponent is $\eta(q) = c q^2  \tau^2 q^2 [2\gamma_E+\psi(q)+\psi(q)]$ in terms of the digamma function $\psi$, where $c$ is nonuniversal and $\gamma_E$ is the Euler constant. The correlation function shows a resonant deep at $q=1$, corresponding to fermion operators in the dual picture, which should bevisible in Bragg scattering experiments."
D. Merlini, "The Riemann magneton of
the primes" (preprint 04/04)
[abstract:] "We present a calculation involving a function related
to the Riemann Zeta function and suggested by two recent works
concerning the Riemann Hypothesis: one by Balazard, Saias and Yor and
the other by Volchkov. We define an integral m(r)
involving the Zeta function in the complex variable s = r
+ it and find a particularly interesting expression for
m(r) which is rigorous at least in some range of r.
In such a range we find that there are two discontinuities of the
derivative m'(r) at r = 1 and r = 0, which
we calculate exactly. The jump at r = 1 is given by 4*Pi. The
validity of the expression for m(r) up to r =
1/2 is equivalent to the truth of the Riemann Hypothesis (RH).
Assuming RH the expression for m (r) gives m = 0
at r = 1/2 and the slope m'(r) = Pi*(1 + gamma) =
4.95 at r = 1/2 (where gamma = 0.577215... is the Euler
constant). As a consequence, if the expression for m(r)
can be continued up to r = 1/2, then if we interpret
m(r) as a magnetization in the presence of a magnetic
field h = r  1/2 (or as a "free energy" at inverse
temperature beta proportional to r), there is a first order
phase transition at r = 1/2 (h = 0) with a jump of
m'(r) given by 2*Pi times the first Lin coefficient
lambda_1 = [1+gamma/2(1/2)ln(4*Pi)] = 0.0230957. Independently of the
RH, by looking at the behavior of the convergent Taylor expansion of
m(r) at r = 1, m(r = 1/2+) as well
as the first Lin coefficient may be evaluated using the Euler product
formula, in terms of the primes. This gives further evidence for the
possible truth of the Riemann Hypothesis."

related to the Riemann Hypothesis with the primes into the critical Strip" (preprint 03/2008)
[abstract:] "In this note concerning integrals involving the logarithm of the Riemann Zeta function, we extend some treatments
given in previous pioneering works on the subject and introduce a more general set of Lorentz measures. We first obtain two new
equivalent formulations of the Riemann Hypothesis (RH). Then with a special choice of the measure we formulate the RH as a
'hidden symmetry', a global symmetry which connects the region outside the critical strip with that inside the critical strip. The
Zeta function with all the primes appears as argument of the Zeta function in the critical strip. We then illustrate the treatment by a
simple numerical experiment. The representation we obtain go a little more in the direction to believe that RH may eventually be true."

(preprint 03/2008)
[abstract:] "We point out an interesting occurrence of the sine kernel in connection with the shifted moments of the Riemann
zetafunction along the critical line. We establish this occurrence rigorously for the shifted second moment and, under some constraints
on the shifts, for the shifted fourth moment. Our proofs of these results closely follow the classical proofs for the nonshifted moments of
the Riemann zetafunction. Furthermore, we conjecture that the sine kernel also occurs in connection with the higher (even) shifted
moments and show that this conjecture is closely related to a recent conjecture by Conrey, Farmer, Keating, Rubinstein, and Snaith."

[abstract:] "Conrey, Farmer, Keating, Rubinstein, and Snaith recently conjectured formulas for the full asymptotics of the moments of $L$functions. In the case of the Riemann zeta function, their conjecture states that the $2k$th absolute moment of zeta on the critical line is asymptotically given by a certain $2k$fold residue integral. This residue integral can be expressed as a polynomial of degree $k^2$, whose coefficients are given in exact form by elaborate and complicated formulas. In this article, uniform asymptotics for roughly the first $k$ coefficients of the moment polynomial are derived. Numerical data to support our asymptotic formula are presented. An application to bounding the maximal size of the zeta function is considered."

[abstract:] "To evaluate Riemann's zeta function is important for many investigations related to the area of number theory, and to have quickly converging series at hand in particular. We investigate a class of summation formulae and find, as a special case, a new proof of a rapidly converging series for the Riemann zeta function. The series converges in the entire complex plane, its rate of convergence being significantly faster than comparable representations, and so is a useful basis for evaluation algorithms. The evaluation of corresponding coefficients is not problematic, and precise convergence rates are elaborated in detail. The globally converging series obtained allow to reduce Riemann's hypothesis to similar properties on polynomials. And interestingly, Laguerre's polynomials form a kind of leitmotif through all sections."

[abstract:] "What is the dimension of a smooth family of complex Hadamard matrices including the Fourier matrix? We address this problem with a power series expansion. Studying all dimensions up to 100 we find that the first order result is misleading unless the dimension is 6, or a power of a prime. In general the answer depends critically on the prime number decomposition of the dimension. Our results suggest that a general theory is possible. We discuss the case of dimension 12 in detail, and argue that the solution consists of two 13dimensional families intersecting in a previously known 9dimensional family. A precise conjecture for all dimensions equal to a prime times another prime squared is formulated."

Criteria are described for constructing a suitable quotient function of these, with properties advantageous for establishing an accessible proof that $\zeta(s)$ must also have all its zeros on the critical line: the celebrated Riemann hypothesis. While the argument put forward is not at the level of rigour required to constitute a full proof of the Riemann hypothesis, it should convince nonspecialists that it must hold."

With a rescaled complex argument, this is denoted here by ${\cal T}_(s)$, and is considered together with a counterpart function ${\cal T}_+(s)$, symmetric rather than antisymmetric about the critical line. We prove that ${\cal T}_+(s)$ has all its zeros on the critical line, and that the zeros of both functions are all of first order. We establish a link between the zeros of ${\cal T}_(s)$ and of ${\cal T}_+(s)$ with those of the zeros of the Riemann zeta function $\zeta(2 s1)$, which enables us to prove that, if the Riemann hypothesis holds, then the distribution function of the zeros of $\zeta (2 s1)$ agrees with those for ${\cal T}_(s)$ and of ${\cal T}_+(s)$ in all terms which do not remain finite as $t\rightarrow \infty$."

This sum can be represented in terms of the product of the Riemann zeta function and the Dirichlet beta function, so that the assertion that all its nontrivial zeros lie on the critical line is a particular case of the Generalised Riemann Hypothesis (GRH). It is shown that a new necessary and sufficient condition for this special case of the GRH to hold is that a particular set of equimodular and equiargument contours of a ratio of MacDonald function double sums intersect only on the critical line. It is further shown that these contours could only intersect off the critical line on the boundary of discrete regions of the complex plane called 'inner islands'. Numerical investigations are described related to this geometrical condition, and it is shown that for the first ten thousand zeros of both the zeta function and the beta function over 70% of zeros lie outside the inner islands, and thus would be guaranteed to lie on the critical line by the arguments presented here. A new sufficient condition for the Riemann Hypothesis to hold is also presented."

Riemann Hypothesis is true for the zetafunction, it is true for $\xi(s)$. Since $\xi(s)$ is entire, the zeros of $\xi'(s)$, its derivative, would then
also satisfy a Riemann Hypothesis. We investigate the pair correlation function of the zeros of $\xi'(s)$ under the assumption that the
Riemann Hypothesis is true. We then deduce consequences about the size of gaps between these zeros and the proportion of these zeros
that are simple."

K.H. Knuth, "Measuring on lattices" (Presented at the 29th International Workshop on Bayesian and Maximum Entropy Methods in Science and Engineering: MaxEnt 2009)
[abstract:] "Previous derivations of the sum and product rules of probability theory relied on the algebraic properties of Boolean logic. Here they are derived within a more general framework based on lattice theory. The result is a new foundation of probability theory that encompasses and generalizes both the Cox and Kolmogorov formulations. In this picture probability is a bivaluation defined on a lattice of statements that quantifies the degree to which one statement implies another. The sum rule is a constraint equation that ensures that valuations are assigned so as to not violate associativity of the lattice join and meet. The product rule is much more interesting in that there are actually two product rules: one is a constraint equation arises from associativity of the direct products of lattices, and the other a constraint equation derived from associativity of changes of context. The generality of this formalism enables one to derive the traditionally assumed condition of additivity in measure theory, as well introduce a general notion of product. To illustrate the generic utility of this novel latticetheoretic foundation of measure, the sum and product rules are applied to number theory. Further application of these concepts to understand the foundation of quantum mechanics is described in a joint paper in this proceedings."

specific behavior of the primes. We employ p^{1}(x) to find approximate solutions of Diophantine

We propose a variation on this problem: studying the asymptotics of the measure of an integer lattice of affine planes inside a ball. The first term is the volume of the ball; we study the size of the remainder term. While the classical problem is equivalent to counting eigenvalues of the Laplace operator on the torus, our variation corresponds to the integrated density of states of the Laplace operator on the product of a torus with Euclidean space. The asymptotics we obtain are then used to compute the density of states of the magnetic Schrödinger operator."

Multiboundary entanglement in Chern–Simons theory and link invariants" (preprint 11/2016)
[abstract:] "We consider Chern–Simons theory for gauge group $G$ at level $k$ on 3manifolds $M_n$ with boundary consisting of $n$ topologically linked tori.
The Euclidean path integral on $M_n$ defines a quantum state on the boundary,
in the $n$fold tensor product of the torus Hilbert space. We focus on the case
where $M_n$ is the linkcomplement of some $n$component link inside the
threesphere $S^3$. The entanglement entropies of the resulting states define
new, framingindependent link invariants which are sensitive to the topology of
the chosen link. For the Abelian theory at level $k$ ($G= U(1)_k$) we give a
general formula for the entanglement entropy associated to an arbitrary
$(mnm)$ partition of a generic $n$component link into sublinks. The formula
involves the number of solutions to certain Diophantine equations with
coefficients related to the Gauss linking numbers (mod $k$) between the two
sublinks. This formula connects simple concepts in quantum information theory,
knot theory, and number theory, and shows that entanglement entropy between
sublinks vanishes if and only if they have zero Gauss linking (mod $k$). For $G
= SU(2)_k$, we study various two and three component links. We show that the
2component Hopf link is maximally entangled, and hence analogous to a Bell
pair, and that the Whitehead link, which has zero Gauss linking, nevertheless
has entanglement entropy. Finally, we show that the Borromean rings have a
"Wlike" entanglement structure (i.e., tracing out one torus does not lead to a
separable state), and give examples of other 3component links which have
"GHZlike" entanglement (i.e., tracing out one torus does lead to a separable
state)."

integers, where ${\bf F}(z)$ and ${\bf G}(z)+\log(z) {\bf F}(z)$ are specific solutions of certain hypergeometric
differential equations with maximal unipotent monodromy at $z=0$. We also address the question of finding the largest
integer $u$ such that the Taylor coefficients of ${\bf q}(z)^{1/u}$ are still integers. As consequences, we are able to
prove numerous integrality results for the Taylor coefficients of mirror maps of Calabi–Yau complete intersections in
weighted projective spaces, which improve and refine previous results by Lian and Yau, and by Zudilin. In particular,
we prove the general ''integrality'' conjecture of Zudilin about these mirror maps. A further outcome of the present
study is the determination of the DworkKontsevich sequence $(u_N)_{N\ge1}$, where $u_N$ is the largest integer
such that $q(z)^{1/u_N}$ is a series with integer coefficients, where $q(z)=\exp(F(z)/G(z))$,
$F(z)=\sum_{m=0} ^{\infty} (Nm)! z^m/m!^N$ and $G(z)=\sum_{m=1} ^{\infty} H_{Nm}(Nm)! z^m/m!^N$,
with $H_n$ denoting the $n$th harmonic number, conditional on the conjecture that there are no prime number $p$
and integer $N$ such that the $p$adic valuation of $H_N$ is strictly greater than 3."

of the $N$th roots of unity: an asymptotic expansion for large $N$" (prepring 08/2008)
[abstract:] "We derive the complete asymptotic expansion in terms of powers of $N$ for the Riesz $s$energy of $N$
equally spaced points on the unit circle as $N\to \infty$. For $s\ge 1$, such points form optimal energy $N$point
configurations with respect to the Riesz potential $1/r^{s}$, $s\neq0$, where $r$ is the Euclidean distance between points.
By analytic continuation we deduce the expansion for all complex values of $s$. The Riemann zeta function plays an
essential role in this asymptotic expansion."

[abstract:] "The same bulk twodimensional topological phase can have multiple distinct, fullychiral edge phases. We show that this can occur in the integer quantum Hall states at $\nu = 8$ and $12$, with experimentallytestable consequences. We show that this can occur in Abelian fractional quantum Hall states as well, with the simplest examples being at $\nu = 8/7, 12/11, 8/15, 16/5$. We give a general criterion for the existence of multiple distinct chiral edge phases for the same bulk phase and discuss experimental consequences. Edge phases correspond to lattices while bulk phases correspond to genera of lattices. Since there are typically multiple lattices in a genus, the bulkedge correspondence is typically onetomany; there are usually many stable fully chiral edge phases corresponding to the same bulk. We explain these correspondences using the theory of integral quadratic forms. We show that fermionic systems can have edge phases with only bosonic lowenergy excitations and discuss a fermionic generalization of the relation between bulk topological spins and the central charge. The latter follows from our demonstration that every fermionic topological phase can be represented as a bosonic topological phase, together with some number of filled Landau levels. Our analysis shows that every Abelian topological phase can be decomposed into a tensor product of theories associated with prime numbers $p$ in which every quasiparticle has a topological spin that is a $p^n$th root of unity for some $n$. It also leads to a simple demonstration that all Abelian topological phases can be represented by $U(1)^N$ Chern–Simons theory parameterized by a Kmatrix."

and quantum information" (preprint 07/2008)
[abstract:] "Symmetry adapted bases in quantum chemistry and bases adapted to quantum information share a
common characteristics: both of them are constructed from subspaces of the representation space of the group SO(3)
or its double group (i.e., spinor group) SU(2). We exploit this fact for generating spin bases of relevance for quantum
systems with cyclic symmetry and equally well for quantum information and quantum computation. Our approach is
based on the use of generalized Pauli matrices arising from a polar decomposition of SU(2). This approach leads to a
complete solution for the construction of mutually unbiased bases in the case where the dimension d of the considered
Hilbert subspace is a prime number. We also give the starting point for studying the case where d is the power of a
prime number. A connection of this work with the unitary group U(d) and the Pauli group is brielly underlined."

[abstract:] "This paper continues the work done in Olofsson [Commun. Math. Phys. 286(3):1051–1072, 2009] about the supremum norm of eigenfunctions of desymmetrized quantized cat maps. $N$ will denote the inverse of Planck's constant and we will see that the arithmetic properties of $N$ play an important role. We prove the sharp estimate $\psi _{\infty} = O(N^{1/4})$ for all normalized eigenfunctions and all $N$ outside of a small exceptional set. We are also able to calculate the value of the supremum norms for most of the so called newforms. For a given $N = p^n$ , with $n>2$, the newforms can be divided in two parts (leaving out a small number of them in some cases), the first half all have supremum norm about $2/\sqrt{1\pm 1/p}$ and the supremum norm of the newforms in the second half have at most three different values, all of the order $N^1/6$. The only dependence of $A$ is that the normalization factor is different if $A$ has eigenvectors modulo $p$ or not. We also calculate the joint value distribution of the absolute value of $n$ different newforms."

[abstract:] "We study the nodal length of random toral Laplace eigenfunctions ("arithmetic random waves") restricted to decreasing domains ("shrinking balls"), all the way down to Planck scale. We find that, up to a natural scaling, for "generic" energies the variance of the restricted nodal length obeys the same asymptotic law as the total nodal length, and these are asymptotically fully correlated. This, among other things, allows for a statistical reconstruction of the full toral length based on partial information. One of the key novel ingredients of our work, borrowing from number theory, is the use of bounds for the socalled spectral QuasiCorrelations, i.e. unusually small sums of lattice points lying on the same circle."

[abstract:] "We describe a quantum cryptography protocol with up to twelve fourdimensional ($d = 4$) states generated by a polarization, phase and timeencoding transmitter. This protocol can be experimentally realized with existing technology, drawing from timeencoded and polarizationencoded systems. The protocol is error tolerant and has a quantum bitrate of 2 per transmission, which when combined with state detection efficiency yields a qubit efficiency of up to 1 or double that of BB84{\it like} protocols. As a practical system, our result appears to contradict a fundamental theorem stating that there exists $d + 1$ maximally nonorthogonal bases for a $d$dimensional space where $d$ is the power of a prime number. Evidently, this contradiction has its origin in the difference in the size of the vector spaces spanned by the basis states, semiinfinite in time and phase in our case, vs. a finite number of polarization states alone as previously considered."

to that of the zeta function of the summation expression, but the nonuse of the Möbius function enable us to confirm
a finite behavior of residual terms which means an absence of zeros except for the critical line. Same technique can be
applied to the Lfunction associated to the elliptic curve, and we can deal with the Taylor expansion at the pole in
critical strip which is deeply related to the BirchSwinnertonDyer conjecture."

the limit of the product of some terms derived from the usual Euler product. We also refer to the relation between the Bernoulli number
and $P(z)$, which is an infinite summation of a $z$ power of the inverse primes. When we apply the same technique to the $L$function
associated to an elliptic curve, we can evaluate the power of the Taylor expansion for the function even in the critical strip, which
is deeply related to problems known as the Birch and SwinnertonDyer conjecture and the Beilinson conjecture."

A particular point of elaboration in these developments is the hypergeometric form and its equivalents for certain derivatives of the incomplete Gamma function. Finally, we evaluate certain integrals including $\int_{\tiny{Re} s=c} {{\zeta(s)} \over s} ds$ and $\int_{\tiny{Re} s=c} {{\eta(s)} \over s} ds$, with $\zeta$ the Riemann zeta function and $\eta$ its alternating form."

M. Combescure, "The Mutually Unbiased Bases revisited" (preprint
05/2006)
[abstract:] "The study of Mutually Unbiased Bases continues to be developed vigorously, and presents several challenges in the
Quantum Information Theory. Two orthonormal bases in $\mathbb C^d, B {and} B'$ are said mutually unbiased if $\forall b\in B, b'\in B'$
the scalar product $b\cdot b'$ has modulus $d^{1/2}$. In particular this property has been introduced in order to allow an optimization
of the measurementdriven quantum evolution process of any state $\psi \in \mathbb C^d$ when measured in the mutually unbiased bases
$B\_{j} {of} \mathbb C^d$. At present it is an open problem to find the maximal number of mutually Unbiased Bases when $d$ is not a power
of a prime number.In this article, we revisit the problem of finding Mutually Unbiased Bases (MUB's) in any dimension $d$. The
method is very elementary, using the simple unitary matrices introduced by Schwinger in 1960, together with their diagonalizations. The
Vandermonde matrix based on the $d$th roots of unity plays a major role. This allows us to show the existence of a set of 3 MUB's in any
dimension, to give conditions for existence of more than 3 MUB's for $d$ even or odd number, and to recover the known result of existence
of $d+1$ MUB's for $d$ a prime number. Furthermore the construction of these MUB's is very explicit. As a byproduct, we recover results
about Gauss Sums, known in number theory, but which have apparently not been previously derived from MUB properties."

In case the dimension, $d$, of the considered Hilbert space is a power of a prime number, complete sets of $d+1$ Mutually Unbiased Bases (MUBs) exist. Here, we present a novel method, which uses the graph state formalism to construct MUBs. We show, that for $n$ $p$level systems, with $p$ being prime, one generalized graph state suffices to easily construct the corresponding complete set of $p^n+1$ MUBs. In fact, we show that a single $n$dimensional vector, which is associated to the generalized graph state, can be used to generate the complete set of MUBs and demonstrate that these vectors can be easily determined."

[abstract:] "Packing problems have been a source of fascination for millenia and their study has produced a rich literature that spans numerous disciplines. Investigations of hardparticle packing models have provided basic insights into the structure and bulk properties of condensed phases of matter, including lowtemperature states (e.g., molecular and colloidal liquids, crystals and glasses), multiphase heterogeneous media, granular media, and biological systems. The densest packings are of great interest in pure mathematics, including discrete geometry and number theory. This perspective reviews pertinent theoretical and computational literature concerning the equilibrium, metastable and nonequilibrium packings of hardparticle packings in various Euclidean space dimensions. In the case of jammed packings, emphasis will be placed on the 'geometricstructure' approach, which provides a powerful and unified means to quantitatively characterize individual packings via jamming categories and 'order' maps. It incorporates extremal jammed states, including the densest packings, maximally random jammed states, and lowestdensity jammed structures. Packings of identical spheres, spheres with a size distribution, and nonspherical particles are also surveyed. We close this review by identifying challenges and open questions for future research."

[abstract:] "Dense packings have served as useful models of the structure of liquid, glassy and crystal states of matter, granular media, heterogeneous materials, and biological systems. Probing the symmetries and other mathematical properties of the densest packings is a problem of longstanding interest in discrete geometry and number theory. The preponderance of previous work has focused on spherical particles, and very little is known about dense polyhedral packings. We formulate the problem of generating dense packings of polyhedra within an adaptive fundamental cell subject to periodic boundary conditions as an optimization problem, which we call the Adaptive Shrinking Cell (ASC) scheme. This novel optimization problem is solved here (using a variety of multiparticle initial configurations) to find dense packings of each of the Platonic solids in threedimensional Euclidean space. We find the densest known packings of tetrahedra, octahedra, dodecahedra and icosahedra with densities $0.782...$, $0.947...$, $0.904...$, and $0.836...$, respectively. Unlike the densest tetrahedral packing, which must be a nonBravais lattice packing, the densest packings of the other nontiling Platonic solids that we obtain are their previously known optimal (Bravais) lattice packings. Our simulations results, rigorous upper bounds that we derive, and theoretical arguments lead us to the strong conjecture that the densest packings of the Platonic and Archimedean solids with central symmetry are given by their corresponding densest lattice packings. This is the analog of Kepler's sphere conjecture for these solids."

These formulas lead to nontrivial integrality statements in number theory, as well as to an improved integrality conjecture stronger than the known Mtheory integrality predictions. Furthermore we determine the BPS degeneracies encoded in augmentation polynomials and show their consistency with known colored HOMFLY polynomials. Finally we consider refined BPS degeneracies for knots, determine them from the knowledge of superApolynomials, and verify their integrality.

infinite power series. In geology this traditionally has been done (poorly) using integration, which I show to systematically
underestimate the aggregate effects of individual features that follow a power law distibution of sizes.
I have not seen this aspect of my paper used in later publications (geologists are notoriously weak in numerical and analytical

M. Hippke, et al., "Pulsation period variations in the RRc Lyrae star KIC 5520878" (preprint 09/2014)
(Submitted on 3 Sep 2014)
"Learned et al. proposed that a sufficiently advanced extraterrestrial civilization may tickle Cepheid and RR Lyrae variable stars with a neutrino beam at the right time, thus causing them to trigger early and jogging the otherwise very regular phase of their expansion and contraction. This would turn these stars into beacons to transmit information throughout the galaxy and beyond. The idea is to search for signs of phase modulation (in the regime of short pulse duration) and patterns, which could be indicative of intentional, omnidirectional signaling.
We have performed such a search among variable stars using photometric data from the Kepler space telescope. In the RRc Lyrae star KIC 5520878, we have found two such regimes of long and short pulse durations. The sequence of period lengths, expressed as time series data, is strongly auto correlated, with correlation coefficients of prime numbers being significantly higher (p = 99.8%). Our analysis of this candidate star shows that the prime number oddity originates from two simultaneous pulsation periods and is likely of natural origin.
Simple physical models elucidate the frequency content and asymmetries of the KIC 5520878 light curve.
Despite this SETI null result, we encourage testing other archival and future timeseries photometry for signs of modulated stars. This can be done as a byproduct to the standard analysis, and even partly automated."

properties of concentrated aqueous suspensions of kaolin  application of the multiple ternary
Bingham model", Applied Clay Science 5 (1990) 217228
[abstract:] "Several kaolin samples from Monte Salgueiro (Spain) obtained by hydrocycloning,
wet ball milling and delamination were examined. The specific lateral and basal surface areas
of the kaolinite were calculated from both the specific surface area by the BET method and the
particle size distribution curves. Flow curves of aqueous suspensions (51% w/w) of those
kaolins were obtained by a rotational viscometer of coaxial cylinders with a predetermined
history of flow. To describe the rheological behaviour the mechanical ternary Bingham model
was applied satisfactorily. Its differential equation under the movement conditions has been
integrated according to the flow history selected. The model and consequently the resulting
equation have been generalized linearly. The number of rheological parameters was reduced to
three because of the application of empirical relations among them. These parameters were
ordered according to the Riemann zeta function simplifying the calculation. Rheological
changes produced by mechanical processes can be described using the parameters of the model
which have been correlated with the geometric mean diameter, specific surface area and
cationic exchange capacity by multiple regression."

Markov process leading an equilibrium described by a probabilistic equation used commonly in the insurance and financial mathematics.

"On the motion of
zeros of zeta functions"
"The motion in the complex plane of the zeros to various zeta
functions is investigated numerically. First the Hurwitz zeta function
is considered and an accurate formula for the distribution of its
zeros is suggested. Then functions which are linear combinations of
different Hurwitz zeta functions, and have a symmetric distribution
of their zeros with respect to the critical line, are examined.
Finally the existence of the hypothetical nontrivial Riemann zeros
with Re(s) /neq 1/2 is discussed."
L. Alexandrov, "On the
nonasymptotic prime number distribution"
[abstract:] "The objective of this paper is to introduce an approach to the study of the nonasymptotic distribution
of prime numbers. The natural numbers are represented by theorem 1 in the matrix form ^2N. The first column of the
infinite matrix ^2N starts with the unit and contains all composite numbers in ascending order.The infinite rows of this
matrix except for the first elements contain prime numbers only, which are determined by an uniform recurrence law.
At least one of the elements of the twin pairs of prime numbers is an element of the second column of the matrix ^2N
(theorem 3). The basic information on the nonasymptotic prime number distribution is contained in the distribution of
the elements of the second column of the matrix ^2N."

symmetric structure and its relation to the twin prime infinitude and an improved prime number theorem (preprint
2006)
[abstract:] "Due to the sieving process represented by a Secondary Sieving Map; during the generation of the
prime numbers, geometric structures with definite symmetries are formed which become evident through their
geometrical representations. The study of these structures allows the development of a constructive prime
generating formula. This defines a mean prime density yielding a second order recursive and discrete prime
producing formula and a second order differential equation whose solutions produce an improved Prime Number
Theorem. Applying these results to twin prime pairs is possible to generate a Twin Prime Number Theorem and
important conclusions about the infinitude of the twin primes."

sphere determinants and Glaisher KinkelinBendersky constants"
[abstract:] "Summations and relations involving the Hurwitz and Riemann zetafunctions are
extended first to Barnes zetafunctions and then to zetafunctions of general type. The
analysis is motivated by the evaluation of determinants on spheres which are treated both by a
direct expansion method and by regularised sums. Comments on existing calculations are made. A
KaluzaKlein technique is introduced providing a determinant interpretation of the
GlaisherKinkelinBendersky constants which are then generalised to arbitrary zetafunctions.
This technique allows an improved treatment of sphere determinants."

cluster on multiples of 6. Recently it was shown that the frequency of the gaps between
the gaps is lower for multiples of 6 than for other values (P. Kumar et. al., "Information entropy and correlation in prime numbers"). This paper
investigates "higher moments" of the prime number series and shows that they exhibit
certain peculiarities. In order to remove doubts as to whether these peculiarities are
related to the known clustering of the gaps on multiples of 6, the results are compared
to a benchmark series of "simulated gaps"."

role. In the slightly less elementary sphere, we find tools from analysis,
such as Poisson summation, generating function methods, Cauchy's residue
theorem, asymptotic methods, and the fast Fourier transform. We then

M.K.H. Kiessling, "Order and chaos in some trigonometric series" (preprint 06/2012)
[abstract:] "The oneparameter family of deterministic trigonometric series $\pzcS_p: t\mapsto \sum_{n\in\Nset}\sin(n^{{p}}t)$, $p>1$, is shown to exhibit both order and apparent chaos. It is proved that $\pzcS_p(t) = \alpha_p\rm{sign}(t)t^{1/{p}}+O(t^{1/{(p+1)}})\;\forall\;t\in\Rset$, with explicitly computed constant $\alpha_p$. A wellmotivated conjecture is formulated concerning the seemingly chaotic fluctuations about this overall trend, to the effect that these fluctuations, when properly scaled, converge in distribution to a standard Gaussian when $t\to\infty$, provided that $p$ is irrational; no conjecture has been forthcoming for rational $p$. Moreover, the interesting relationship of the asymptotics of $\pzcS_p(t)$ to properties of the Riemann $\zeta$ function is worked out."
C.H.A. Cheng, R. GraneroBelinchon, S. Shkoller and J. Wilkening, "Rigorous asymptotic models of water waves" (preprint 07/2018)
"We develop a rigorous asymptotic derivation for two mathematical models of water waves that capture the full nonlinearity of the Euler equations up to quadratic and cubic interactions, respectively. Specifically, letting epsilon denote an asymptotic parameter denoting the steepness of the water wave, we use a Stokes expansion in epsilon to derive a set of linear recursion relations for the tangential component of velocity, the stream function, and the water wave parameterization. The solution of the water waves system is obtained as an infinite sum of solutions to linear problems at each $\epsilon^k$ level, and truncation of this series leads to our two asymptotic models, that we call the quadratic and cubic $h$models. Using the growth rate of the Catalan numbers (from number theory), we prove wellposedness of the $h$models in spaces of analytic functions, and prove error bounds for solutions of the $h$models compared against solutions of the water waves system. We also show that the Craig–Sulem models of water waves can be obtained from our asymptotic procedure and that their WW2 model is wellposed in our functional framework. We then develop a novel numerical algorithm to solve the quadratic and cubic $h$models as well as the full water waves system. For three very different examples, we show that the agreement between the model equations and the water waves solution is excellent, even when the wave steepness is quite large. We also present a numerical example of corner formation for water waves."
C.M. Newman and W. Wu, "Constants of de Bruijn–Newman type in analytic number theory and statistical physics" (preprint 01/2019)
[abstract:] "One formulation in 1859 of the Riemann Hypothesis (RH) was that the Fourier transform $H_f(z)$ of $f$ for $z \in \mathbb{C}$ has only real zeros when
$f(t)$ is a specific function $\Phi(t)$. Pólya's 1920s approach to RH
extended $H_f$ to $H_{f,\lambda}$, the Fourier transform of $e^{\lambda t^2}
f(t)$. We review developments of this approach to RH and related ones in
statistical physics where $f(t)$ is replaced by a measure $d \rho(t)$.
Pólya's work together with 1950 and 1976 results of de Bruijn and Newman,
respectively, imply the existence of a finite constant $\Lambda_{DN} =
\Lambda_{DN}(\Phi)$ in $(\infty, 1/2]$ such that $H_{\Phi,\lambda}$ has only
real zeros if and only if $\lambda\geq \Lambda_{DN}$; RH is then equivalent to
$\Lambda_{DN} \leq 0$. Recent developments include the Rodgers and Tao proof of
the 1976 conjecture that $\Lamda_{DN} \geq 0$ (that RH, if true, is only
barely so) and the Polymath 15 project improving the $1/2$ upper bound to about $0.22$. We also present examples of $\rho$'s with differing $H_{\rho,\lambda}$
and $\Lambda_{DN}(\rho)$ behaviors; some of these are new and based on a
recent weak convergence theorem of the authors."
A.R. Fazely, "Primeindex parametrization for total neutrinonucleon cross sections and $pp$ cross sections" (preprint 08/19)
"A prime number based parametrization for total neutrinonucleon cross section
is presented. The method employs the relation between prime numbers and their
indices to reproduce neutrino cross sections for neutrino energies from the
$MeV$ to the $PeV$ regions where experimental data are available. This
primeindex relation provides estimates of the neutrinonucleon cross sections valid across many decades of neutrino energy scales. The $PeV$ data are from the recently published astrophysical $\nu_{\mu} +\bar{\nu_{\mu}}$ rates in the IceCube detector as well as neutrinonucleon cross section measurements. A similar method has been employed for high energy $pp$ cross sections which explains the $(\ln s)^2$ parametrization first proposed by Heisenberg."
O. Fuentealba, H.A. González, M. Pino and R. Troncoso, "The anisotropic chiral boson" (preprint 09/19)
[abstract:] "We construct the theory of a chiral boson with anisotropic scaling, characterized by a dynamical exponent $z$, whose action reduces to that of Floreanini and Jackiw in the isotropic case ($z=1$). The standard free boson with Lifshitz scaling is recovered when both chiralities are nonlocally combined. Its canonical structure and symmetries are also analyzed. As in the isotropic case, the theory is also endowed with a current algebra. Noteworthy, the standard conformal symmetry is shown to be still present, but realized in a nonlocal way. The exact form of the partition function at finite temperature is obtained from the path integral, as well as from the trace over $\hat{u}(1)$ descendants. It is essentially given by the generating function of the number of partitions of an integer into $z$th powers, being a wellknown object in number theory. Thus, the asymptotic growth of the number of states at fixed energy, including subleading corrections, can be obtained from the appropriate extension of the renowned result of Hardy and Ramanujan."
L.A. Takhtajan, "Etudes of the resolvent" (preprint 04/2020)
[abstract:] "Based on the notion of the resolvent and on the Hilbert identities, this paper presents a number of classical results in the theory of differential operators and some of their applications to the theory of automorphic functions and number theory from a unified point of view. For instance, for the Sturm–Liouville operator there is a derivation of the Gelfand–Levitan trace formula, and for the onedimensional Schroedinger operator a derivation of Faddeev's formula for the characteristic determinant and the Zakharov–Faddeev trace identities. Recent results on the spectral theory of a certain functionaldifference operator arising in conformal field theory are then presented. The last section of the survey is devoted to the Laplace operator on a fundamental domain of a Fuchsian group of the first kind on the Lobachevsky plane. An algebraic scheme is given for proving analytic continuation of the integral kernel of the resolvent of the Laplace operator and the Eisenstein–Maass series. In conclusion, there is a discussion of the relation between the values of the Eisenstein–Maass series at Heegner points and Dedekind zetafunctions of imaginary quadratic fields, and it is explained why pseudocuspforms for the case of the modular group do not provide any information about the zeros of the Riemann zetafunction."
B. Mukhametzhanov and S. Pal, "Beurling–Selberg extremization and modular bootstrap at high energies" (preprint 03/2020)
[abstract:] "We consider previously derived upper and lower bounds on the number of operators in a window of scaling dimensions $[\Delta\delta,\Delta+\delta]$ at asymptotically large $\Delta$ in $2d$ unitary modular invariant CFTs. These bounds depend on a choice of functions that majorize and minorize the characteristic function of the interval $[\Delta\delta,\Delta+\delta]$ and have Fourier transforms of finite support. The optimization of the bounds over this choice turns out to be exactly the Beurling–Selberg extremization problem, widely known in analytic number theory. We review solutions of this problem and present the corresponding bounds on the number of operators for any $\delta\geq 0$. When $2\delta \in \mathbb{Z}_{\geq 0}$ the bounds are saturated by known partition functions with integerspaced spectra. Similar results apply to operators of fixed spin and Virasoro primaries in $c > 1$ theories."

$L^2(\mathbf{Q}_p)$ of complex valued squareintegrable functions on the $p$adic number field $\mathbf{Q}_p$. The Riemann zetafunction and the related Dirichlet $L$functions can be expressed as a trace of these operators on a subspace of $L^2(\mathbf{Q}_p)$. We also extend this to the $L$functions associated with modular (cusp) forms. Wavelets on $L^2(\mathbf{Q}_p)$ are common sets of eigenfunctions of these operators."

"The model concepts enable to show that the continuum real number field
contains unique structures, namely prime numbers which are analogous
to the dominant eddies in the eddy continuum in turbulent fluid flows. In
this paper it is shown that the prime number frequency spectrum follows
quantumlike mechanical laws."

"Cantorian fractal patterns, quantumlike chaos and prime numbers in
atmospheric flows"
"The quantumlike chaos in atmospheric flows can be quantified in terms
of the following mathematical functions/concepts: (1) The fractal structure
of the flow pattern is resolved into an overall logarithmic spiral trajectory with the quasiperiodic Penrose tiling pattern for the
internal structure and is equivalent to a hierarchy of vortices. The
incorporation of Fibonacci mathematical series, representative of ramified
bifurcations, indicates ordered growth of fractal patterns. (2) The steady
state emergence of progressively larger fractal structures incorporates
unique primary perturbation domains of progressively increasing number
equal to z/ln z where z, the length step growth stage
is equal to the length scale ratio of large eddy to turbulent eddy. In
number theory, z/ln z gives the number of primes less than
z. The model also predicts that z/ln z represents the
normalised cumulative variance spectrum of the eddies and which follows
statistical normal distribution. The important result of the study is that
the prime number spectrum is the same as the eddy energy spectrum for
quantumlike chaos in atmospheric flows."
