摘　　要：研究了存在Kerr介质时依赖强度耦合单模压缩真空场与耦合双原子非共振相互作用系统中原子的偶极压缩,运用数值方法讨论了系统参数对原子偶极压缩的影响.结果表明:Kerr介质、失谐量、原子间相互作用、光场初始压缩因子和原子的初始状态对原子偶极压缩有较大的影响.In this paper,the atomic dipole squeezing in the non-resonance system of single-model squeezed vacuum field interacting with two coupling atoms via intensity-dependent coupling in Kerr medium are investigated.By using the numerical method,the relations between the atomic dipole squeezing and the coupling parameter of the system are discussed.The results show that the atomic dipole squeezing depend on the Kerr effect,the detuning,the dipole-dipole interaction between atoms,the initial squeezed parameter of the light and the atomic initial state.
