Free and dissipative evolution of squeezed and displaced number states in the third-order nonlinear oscillator
Vlasta Peřinová, J. Křepelka · Physical Review A · 1993
The evolution of squeezed and displaced number states in the free and dissipative third-order nonlinear oscillator is investigated from the point of view of nonclassical phenomena as the number squeezing in both the strong and the weak sense, the principal squeezing of vacuum fluctuations, and the generation of superposition states. A destructive effect of losses on quantum coherence is demonstrated.
