We perform a detailed numerical study of diffusion in the ɛ stadium of Bunimovich, and propose an empirical model of the local and global diffusion for various values of ɛ with the following conclusions: (i) the diffusion is normal for all values of ɛ (≤0.3) and all initial conditions, (ii) the diffusion constant is a parabolic function of the momentum (i.e., we have inhomogeneous diffusion), (iii) the model describes the diffusion very well including the boundary effects, (iv) the approach to… 

Spectral form factors and dynamical localization

: Quantum dynamical localization occurs when quantum interference stops the diffusion of wave packets in momentum space. The expectation is that dynamical localization will occur when the typical

Diffusion phenomena in a mixed phase space.

We show that, in strongly chaotic dynamical systems, the average particle velocity can be calculated analytically by consideration of Brownian dynamics in a phase space, the method of images, and the

Structure, size, and statistical properties of chaotic components in a mixed-type Hamiltonian system.

A detailed study of the chaotic component in mixed-type Hamiltonian systems on the example of a family of billiards finds the standard deviation of cell recurrence time is found to be a good quantifier of stickiness on a global scale.

Statistical properties of the localization measure of chaotic eigenstates and the spectral statistics in a mixed-type billiard.

The quantum localization in the chaotic eigenstates of a billiard with mixed-type phase space is studied, and it is shown that A is linearly related to normalized inverse participation ratio, similar to the quantum kicked rotator and the stadium billiard.

New universal aspects of diffusion in strongly chaotic systems

We study some new universal aspects of diffusion in chaotic systems, especially those having very large Lyapunov coefficients on the chaotic (indecomposable, topologically transitive) component. We

This work shows that the requirement that a particle's distribution function approach the Boltzmann distribution at long times dictates that a drift term must be added to the Langevin equation, and derives a path integral representation for arbitrary interpretation of the noise.

A more refined theory of the localization length in the quantum kicked rotator and in similar Floquet systems is called for, where not only the mean value of the inverse of the localized length L but also its (Gaussian) distribution is predicted, in particular the variance.

Diffusion and Localization in Chaotic Billiards.

The classical diffusive process which takes place in a chaotic billiard is studied analytically and numerically to estimate the conditions under which the statistical properties of eigenvalues and eigenfunctions can be described by Random Matrix Theory.

In this work we study the level spacing distribution in the classically mixed-type quantum systems (which are generic), exhibiting regular motion on invariant tori for some initial conditions and
