Kerr-type nonlinear quantum oscillator - quantum correlations, chaotic and regular dynamics

摘要

We propose the second-order correlation function g~((2))as an indicator of quantum chaotic evolution. We discuss a nonlinear Kerr-like oscillator's system excited by a series of ultra-short coherent pulses. For such model, we study the time-evolution of the function g~((2)) for various values of the strength of excitation which corresponds to the regular and chaotic behaviors of the classical counterpart of the Kerr-like quantum system.
