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.

Time evolution of squeezing and antibunching effects in a nuclear model known as the three-level Lipkin model is analyzed. The two effects occur in the regime of classically regular motion, but disappear in the regime of classically chaotic motion, which is similar to that obtained in a spin-boson model (another quantum chaotic system). \textcopyright{} 1996 The American Physical Society.
