Squeezed states and squeezed number states of a driven harmonic oscillator with time-dependent frequency
【摘要】 研究了频率随时间变化的受迫谐振子系统的不变量和不变量的一般形式 ,并利用基本不变量构造了此含时系统的压缩态和压缩数态。
【Abstract】 The basic invariants and the general forms of the invariants for a driven harmonic oscillator with time dependent frequency are studied. With the help of the basic invariant, the squeezed states and squeezed number states for this time-dependent system are also constructed.
