Quantum-Classical Correspondence and Nonclassical State Generation in Dissipative Quantum Optical Systems

Original language description

We develop a semiclassical method to determine the nonlinear dynamics of dissipative quantum optical systems in the limit of large number of photons N, it is based on the 1/N-expansion and the quantum-classical correspondence. The method is used to tackle two problems: the study of the dynamics of nonclassical stte generation in higher order anharmonic dissipative oscillators and the establishment of the difference between the quantum and classical dynmics of the second-harmonic generation in a self-pulsing regime. In addressing the first problem, we obtain an explicit time dependence of the squeezing and the Fano factor for an arbitrary degree of anharmonism in the short-time approximation. For the second problem, we analytically find a characteristictime scale at which the quantum dynamics differs insignificantly from the classical one.
