Squeezing Effect of the Field Interacting with a Moving Atom

采用量子光学中时间演化算符方法 ,研究了与运动原子相互作用的场的压缩效应 ,揭示了光场的初始平均光子数和场模结构参数对光场压缩特性的影响 ,结果表明 :适当选择系统参数 ,可获得在时间上持续压缩的压缩光。

The squeezing effect of the field intera cting with a moving atom is investigated by means of the evolution operator in quantum optics. The influence of the initial average photon number and field model structure parameter on the squeezing property of the field is studied. It is shown that the field may exhibit long time squeezing effect by chosing system parameters appropriately.
