Hybrid phase-space – Fock-space approach to evolution of a driven nonlinear resonator

Abstract

We analyze the quantum evolution of a weakly nonlinear resonator due to a classical near-resonant drive and damping. The resonator nonlinearity leads to squeezing and heating of the resonator state. Using a hybrid phase-space–Fock-space representation for the resonator state within the Gaussian approximation, we derive evolution equations for the four… (More)
