摘　　要：利用反Tavis-Cummings模型研究了初始处于纠缠态的两个全同二能级原子与单模二项式光场的相互作用.在强经典驱动和大失谐的情况下,原子与光场的相互作用可以转化为有效的Tavis-Cummings模型和反Tavis-Cummings模型.主要是研究了反Tavis-Cummings模型下纠缠原子布居的时间演化.结果表明,纠缠原子布居的时间演化和光场的强度以及光场的初始状态有关.The interaction between two identical two-level atoms and single mode binomial light field is studied in anti-Tavis-Cummings model, and the atoms stay in entangled state initially. When the classi- cal field is strong enough, the interaction between the atoms and the light field can turn into an effective anti-Tavis-Cummings model and Tavis-Cummings model under the condition of large detuning. In this paper, we mainly study the population of entangled atoms in anti-Tavis-Cummings model. The results show that the evolution of atomic por）ulation is depend on intensity and initial state of light field.
