Abstract

A model of a nonlinear, damped kicked oscillator is discussed. For such a model intra-mode correlations described by mutual information parameter I[α] based on the Wehrl entropy are considered. Furthermore, the system’s quantum evolution is compared to its classical counterpart. The mutual information parameter is discussed as a proposal for quantum chaos’ witness.
