The Characteristic Times of Violation of Quasiclassical Approximation for Integrable Boson and Spinolutions for different boson and spin systems. As a first step we consider in this section the application of the considered above c-number equations for quantum integrable boson and spin systems in quasiclassical region of parameters. We derive one of the main characteristic dynamical parameter, na

Namely, the transition to chaos takes place under conditions of strong interaction of NRs in classical Hamiltonian systems . These concepts also appear to be useful in the investigation of quantum chaos in Hamiltonian systems . In t

At resonance . (r,q are integers) the effect of perturbation is especially strong. Recent investigations of system (9.1) in the classical limi

Characteristic Times for Chaotic Dynamics in Wigner Representation,ical region quantum effects can play an essential role. One of the main phenomena is the existence of the classical-quantum time-scale . ∼ ln ., (. ∼ 1/.) for classically chaotic systems. Another important quantum effect in the region of parameters of quantum chaos is the suppression of quantum diff

Actually, in an experimental realization in the optical and even in the microwave frequency regions the condition Λ > 1 is difficult to achieve. That is why, below, in this section we consider, following , a modification of the quantum system with the Hamiltonian (11.2), where stro
