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.

I give a new derivation of the Explicit Formula for an arbitrary number field and abelian DirichletHecke character, which treats all primes in exactly the same way, whether they are discrete or archimedean, and also ramified or not. This is followed with a local study of a Hilbert space operator, the “conductor operator”, which is expressed as H = log(x)+log(y) (where x and y are Fourier dual variables on a νadic completion of the number field). I also study the commutator operator K = i [log(y), log(x)] (which shares with H the property of complete dilation invariance, and turns out to be bounded), as well as the higher commutator operators. The generalized eigenvalues of these operators are given by the derivatives on the critical line of the TateGel’fandGraev Gamma function, which itself is in fact closely related to the additive Fourier Transform viewed in multiplicative terms. This spectral analysis is thus a natural continuation to Tate’s Thesis in its local aspects.

We rewrite the zerocounting formula within the critical strip of the Riemann zeta function as a cumulative density distribution; this subsequently allows us to derive an integral expression for the Li coefficients associated with the Riemann ξfunction and, in particular, indicate that their positivity criterion is obeyed, whereby entailing the criticality of the nontrivial zeros.

Negative correlations in the distribution of prime numbers are found to display a scale invariance. This occurs in conjunction with a nonstationary behavior. We compare the prime number series to a type of fractional Brownian motion which incorporates both the scale invariance and the nonstationary behavior. Interesting discrepancies remain. The scale invariance also appears to imply the Riemann hypothesis and we study the use of the former as a test of the latter. 1 Scale Invariance The distribution of prime numbers has been a source of fascination for mathematicians for centuries. Of interest to physicists is the fact that the distribution of prime numbers exhibits certain characteristics that are usually associated with chaotic and complex systems. The data on the prime number series is plentiful and a surprisingly rich structure is uncovered when this data is probed in various ways [1]. The closely associated zeros of the Riemann zeta function have been studied even more intensely from a physics viewpoint [2]. We shall show that prime number differences display a scale invariance in their correlations. The differences also display a nonstationary behavior that coexists with the scale invariance. We shall identify a random process, fractional Brownian motion of a lesser known type, that displays these and other properties of the prime number series. But there are still quantitative differences which suggest that a further generalization of fractional Brownian motion remains to be developed. The resolution of this puzzle could have practical value for descriptions of complex systems in physics and economics. In addition we shall describe how a breakdown of the Riemann hypothesis would not be compatible with the preservation of scale invariance.

We derive an exact expression for the twopoint correlation function for quantum star graphs in the limit as the number of bonds tends to infinity. This turns out to be identical to the corresponding result for certain ˇ Seba billiards in the semiclassical limit. Reasons for this are discussed. The formula we derive is also shown to be equivalent to a series expansion for the form factor — the Fourier transform of the twopoint correlation function — previously calculated using periodic The statistical distribution of quantum energy levels is a much studied topic. It has been conjectured that generic, classically integrable systems give rise to uncorrelated quantum spectra [1], while the energy levels of generic classically chaotic systems have the same statistical properties as the eigenvalues of

Abstract. A possible connection between quantum computing and Zeta functions of finite field equations is described. Inspired by the spectral approach to the Riemann conjecture, the assumption is that the zeroes of such Zeta functions correspond to the eigenvalues of finite dimensional unitary operators of natural quantum mechanical systems. The notion of universal, efficient quantum computation is used to model the desired quantum systems. Using eigenvalue estimation, such quantum circuits would be able to approximately count the number of solutions of finite field equations with an accuracy that does not appear to be feasible with a classical computer. For certain equations (Fermat hypersurfaces) it is show that one can indeed model their Zeta functions with efficient quantum algorithms, which gives some evidence in favor of the proposal of this article.

An ensemble of 2 × 2 pseudoHermitian random matrices is constructed that possesses real eigenvalues with levelspacing distribution exactly as for the Gaussian unitary ensemble found by Wigner. By a reinterpretation of Connes ’ spectral interpretation of the zeros of Riemann zeta function, we propose to enlarge the scope of search of the Hamiltonian connected with the celebrated Riemann Hypothesis by suggesting that the Hamiltonian could also be PTsymmetric (or pseudoHermitian). PACS Nos: 05.45.+b, 03.65.Ge 1 Riemann Hypothesis (RH) states that all the nontrivial zeros of the Riemann zeta function have the form 1 2 + iσn, lying on a line [1]. This beautiful statement got related to mechanics by the conjecture of Hilbert and Polya, as a result, a search is on for a selfadjoint operator admitting

The rise between successive windings gets sharper as the scaled Planck’s constant decreases. This behaviour can be understood semiclassically. The first two terms of the asymptotic eigenvalue density are the same as those for the density of heights of the Riemann zeros.
