摘　　要：考察了依赖强度耦合的广义Jaynes Cummings模型 .假定初始时光场是相干态、原子处于相干迭加态 .作者发现 ,在相位匹配条件下 ,初始场的相干态展示周期性的复原效应 .同时 ,还证明了在描写光场的相干性方面 ,光场的量子相位与量子相干性是并协的 .Authors examine the generalized Jaynes Cummings model with intensity dependent coupling, with the field initially in a coherent state and the atom initially in a coherent superposition of its states. It is found that the coherent state of original field exhibits periodical revival under phase match condition. Also show the quantum phase and coherence properties of the field are complementary in description of the optical quantum coherence.
