摘　　要：文章研究了在大失谐条件下两全同二能级纠缠原子与相干态光场相互作用过程中系统的原子特性,采用时间演化算符和数值计算方法讨论了系统参数对系统原子特性的影响。研究表明,单模相干光场和两全同二能级纠缠原子在大失谐作用条件下,无论如何调整系统参数,都无法使原子偶极压缩。The property of the atomic interacting with two identical entangled atoms is investigated while the interaction between the atoms and the cavity mode is a highly detuned one. The effect of the system parameters on the property of the optical field is discussed via time evolution operators and numerical calculation. The result shows that, in this highly detuned system, the atom cannot achieve the dipole squeezing effect under any system parameter.
