Three-mode system of nonlinear quantum oscillators and quantum correlations

Abstract

We discuss a chain of three nonlinear oscillators excited by an external field. We show that during system’s evolution squeezed states can be generated in all three modes. Such generated squeezing appears simultaneously in all modes but for different quadratures. We show that degree of the squeezing and time of its appearance depend on the values of the parameters determining strengths of external and internal couplings and dumping of the system.
