Value statistics of chaotic Wigner function
Martin Horvat, Tomaz Prosen
abstract: We study Wigner function value statistics of classically chaotic quantum maps
on compact 2D phase space. We show that the Wigner function statistics of a
random state is a Gaussian, with the mean value becoming negligible compared to
the width in the semi-classical limit. Using numerical example of quantized
sawtooth map we demonstrate that the relaxation of time-dependent Wigner
function statistics, starting from a coherent initial state, takes place on a
logarithmically short log (hbar) time scale.
