摘　　要：利用多光子反Jaynes-Cummings模型研究了单模相干光场与两个全同的纠缠二能级原子相互作用时纠缠原子的布居数演化,并讨论相干光场的平均光子数及跃迁光子数对纠缠原子布居数产生的影响。结果表明:随着相干光场平均光子数的增加纠缠二能级原子处于激发态和基态的几率差减小,布居数的振荡曲线整体上移;随着跃迁光子数的增加纠缠二能级原子处于激发态和基态的几率差增大,振荡曲线整体下移。When single mode coherent light field interacts with two identical entangled two-level atoms, the population number evolution of entangled atoms is studied by means of the multi-photon anti-Jaynes-Cummings model.Influence of average photon number of the coherent light field and transition photon number on the population number evolution of entangled atoms was discussed.The result indicates that the probability difference of the excited state and ground state of the entangled two-level atoms will decrease and whole of oscillation curves of the population number will rise with increasing of average photon number of coherent light field.With the increasing of the transition photon number,the probability difference of the excited state and ground state of the entangled two-level atoms will increase and whole of the oscillation curves of the population number will descend.
