Comparison between formulae for the counting functions of the heights t n of the Riemann zeros and of semiclassical quantum eigenvalues En suggests that the t n are eigenvalues of an (unknown) hermitean operator H, obtained by quantizing a classical dynamical system with hamiltonian H cl . Many features of H cl are provided by the analogy; for example, the "Riemann dynamics" should be chaotic and have periodic orbits whose periods are multiples of logarithms of prime numbers. Statistics of the t n have a similar structure to those of the semiclassical En ; in particular, they display randommatrix universality at short range, and nonuniversal behaviour over longer ranges. Very refined features of the statistics of the t n can be computed accurately from formulae with quantum analogues. The RiemannSiegel formula for the zeta function is described in detail. Its interpretation as a relation between long and short periodic orbits gives further insights into the quantum spectral fluctuations. We speculate that the Riemann dynamics is related to the trajectories generated by the classical hamiltonian H cl = XP.

The focus of this survey paper is on the distribution function FNβ(t) for the largest eigenvalue in the finite N Gaussian Orthogonal Ensemble (GOE, β = 1), the Gaussian Unitary Ensemble (GUE, β = 2), and the Gaussian Symplectic Ensemble (GSE, β = 4) in the edge scaling limit of N → ∞.

The focus of this survey paper is on the distribution function FNβ(t) for the largest eigenvalue in the finite N Gaussian Orthogonal Ensemble (GOE, β = 1), the Gaussian Unitary Ensemble (GUE, β = 2), and the Gaussian Symplectic Ensemble (GSE, β = 4) in the edge scaling limit of N → ∞. These limiting distribution functions are expressible in terms of a particular Painlevé II function. Comparisons are made with finite N simulations as well as a discussion of the universality of these distribution functions. 1.

Abstract. All physical systems in equilibrium obey the laws of thermodynamics. In other words, whatever the precise nature of the interaction between the atoms and molecules at the microscopic level, at the macroscopic level, physical systems exhibit universal behavior in the sense that they are all governed by the same laws and formulae of thermodynamics. In this paper we describe some recent history of universality ideas in physics starting with Wigner’s model for the scattering of neutrons off large nuclei and show how these ideas have led mathematicians to investigate universal behavior for a variety of mathematical systems. This is true not only for systems which have a physical origin, but also for systems which arise in a purely mathematical context such as the Riemann hypothesis, and a version of the card game solitaire called patience sorting. 1.

A detailed discussion of semiclassical trace formulae is presented and it is demonstrated how a regularized trace formula can be derived while dealing only with finite and convergent expressions. Furthermore, several applications of trace formula techniques to quantum chaos are reviewed. Then local spectral statistics, measuring correlations among finitely many eigenvalues, are reviewed and a detailed semiclassical analysis of the number variance is given. Thereafter the transition to global spectral statistics, taking correlations among infinitely many quantum energies into account, is discussed. It is emphasized that the resulting limit distributions depend on the way one passes to the global scale. A conjecture on the distribution of the fluctuations of the spectral staircase is explained in this general context and evidence supporting the conjecture is discussed. 1 Lectures held at the 3rd International Summer School/Conference Let’s face chaos through nonlinear dynamics at

The article reviews recent developments in the theory of fluctuations and correlations of energy levels and eigenfunction amplitudes in diffusive mesoscopic samples. Various spatial geometries are considered, with emphasis on lowdimensional (quasi1D and 2D) systems. Calculations are based on the supermatrix σmodel approach. The method reproduces, in socalled zeromode approximation, the universal random matrix theory (RMT) results for the energylevel and eigenfunction fluctuations. Going beyond this approximation allows us to study systemspecific deviations from universality, which are determined by the diffusive classical dynamics in the system. These deviations are especially strong in the far “tails ” of the distribution function of the eigenfunction amplitudes (as well as of some related quantities, such as local density of states, relaxation time, etc.). These asymptotic “tails ” are governed by anomalously localized states which are formed in rare realizations of the random potential. The deviations of the level and eigenfunction statistics from their RMT form strengthen with increasing disorder and become especially pronounced at the Anderson metalinsulator

We study the levelspacings distribution for eigenvalues of large N \Theta N matrices from the Classical Compact Groups in the scaling limit when the mean distance between nearest eigenvalues equals 1. Defining by jN (s) the number of nearest neighbors spacings, greater than s ? 0 (smaller than s ? o ) we prove functional limit theorem for the process (j N (s) \Gamma IEj N (s))=N 1=2 , giving weak convergence of this distribution to some Gaussian random process on [0; 1) . The limiting Gaussian random process is universal for all Classical Compact Groups. It is Holder continuous with any exponent less than 1=2 : Numerical results suggest it not to be a standard Brownian bridge. Our methods can be also applied to study nlevel spacings distribution.

A quantum dot is a submicronscale conducting device containing up to several thousand electrons. Transport through a quantum dot at low temperatures is a quantumcoherent process. This review focuses on dots in which the electron’s dynamics are chaotic or diffusive, giving rise to statistical properties that reflect the interplay between onebody chaos, quantum interference, and electronelectron
