Negative Wigner functions of nonlinear dissipative oscillator in the pulsed regime

  • Published:
Journal of Contemporary Physics (Armenian Academy of Sciences) Aims and scope

Abstract

Preparation of nonclassical states that are described by negative Wigner functions is studied for an anharmonic oscillator under parametric excitation (AOPE). The over-transient pulsed regime of AOPE driven by a train of Gaussian laser pulses is analyzed. The results are obtained by complete consideration of dissipative and decoherence effects.
