摘　　要：利用全量子理论计算方法,研究两纠缠原子与Number-Phase态量子化辐射场相互作用的动力学行为,分析了光场参数和两纠缠原子纠缠度对原子布居数和原子偶极压缩随时间演化的影响.结果表明:纠缠原子处于不同初态时,原子布居数和原子偶极压缩呈现不同的振荡规律;选取适当的系统参数和原子纠缠度时,原子布居数会表现出周期性的崩塌与复原现象.The dynamical effects in a system which is composed of two-level entangled atoms interac- ting with an intermediate Number-phase state are studied by calculation means of the quantum theory. The influence of the parameters of system and the degree of entanglement of two-level entangled atoms on the time evolution of atomic population and atomic dipole squeezing are analyzed. The result shows that the atomic population and atomic dipole squeezing appear different oscillation when initial state of the entangled atoms is different. The phenomena of collapse followed by periodic revivals of atomic population can be exhibited via choosing appropriate parameters of system and the degree of entanglement.
