应用Pegg-Barnett位相理论,研究了Jaynes-Cummings模型(J-C模型)中压缩真空初态场位相演化特性,具体计算了弱压缩条件下,场的位相几率分布函数及位相涨落,给出了在极坐标中位相几率分布演化曲线,讨论了原子与场相互作用对场的位相性质的影响。

The properties of the phase evolution of an initially squeezed vacuum in the Jaynes-Cummings model are studied by using the Pegg-Barnett phase theory. The phase probability distribution and variance are calculated for weal squeezing. The curres of evolution of the phas probability distribution are given on a polar diagram. The influenses of an atom interacting with squeezed vacuum on the phase properties are discused.
