摘　　要：利用全量子理论并结合数值计算的方法,研究两个二能级原子与双模纠缠相干场相互作用系统的原子布居数演化性质。讨论了跃迁光子数、初始平均光子数、光场纠缠程度及双原子间偶极相互作用对原子布居数演化特性的影响。Time- evolution of the atomic population in the system of two - mode entangled coherent field interacting with two two - level atoms via multiphoton process are investigated by means of quantum theory and numerical method. The effect on atomic population induce by the absorbing or emitting photon number, the mean photon number of initial field, the degree of the entanglement for the entangled coherent field ,and the coupling strength of dipole - dipole interaction between atoms were discussed.
