摘要: In this work we analyze the temporal dynamics of a system comprising an optical cavity filled with nonlinear Kerr medium, whose frequency is allowed to change during time evolution. By exactly solving corresponding time-dependent anharmonic-oscillator Hamiltonian, demonstrate that squeezed coherent-state superpositions can be generated within cavity. Moreover, show squeezing degree produced states may tuned by properly controlling shift cavity, feature might lead interesting studies in field quantum state engineering.
