On A Bosonization Approach To Disordered Systems

In [1] a new bosonization procedure has been illustrated, which allows to express a fermionic gaussian system in terms of commuting variables at the price of introducing an extra dimension. The Fermi-Bose duality principle established in this way has many potential applications also outside the context of gauge field theories in which it has been developed. In this work we present an applicatio...

Spectral spacing correlations for chaotic and disordered systems

New aspects of spectral fluctuations of (quantum) chaotic and diffusive systems are considered, namely autocorrelations of the spacing between consecutive levels or spacing autocovariances. They can be viewed as a discretized two point correlation function. Their behavior results from two different contributions. One corresponds to (universal) random matrix eigenvalue fluctuations, the other to...

Dynamics of perturbations in disordered chaotic systems.

We study the time evolution of perturbations in spatially extended chaotic systems in the presence of quenched disorder. We find that initially random perturbations tend to exponentially localize in space around static pinning centers that are selected by the particular configuration of disorder. The spatiotemporal behavior of typical perturbations deltau(x,t) is analyzed in terms of the Hopf-C...

0 Scattering from Spatially Localized Chaotic and Disordered Systems

A version of scattering theory that was developed many years ago to treat nuclear scattering processes, has provided a powerful tool to study universality in scattering processes involving open quantum systems with underlying classically chaotic dynamics. Recently, it has been used to make random matrix theory predictions concerning the statistical properties of scattering resonances in mesosco...

A Universal Property of Eigenfunctions of Chaotic and Disordered systems

We study the distribution function of ratio of components of eigenfunctions in chaotic and disordered systems. A universal behavior of the form of Lorentzian distribution is found for the distribution function in several models: analytically for the Random Matrix Model and numerically for the Band Random Matrix Model, the Lipkin model, a chaotic quantum billiard and a 1D tight binding model. PA...
