| 摘 要： | 处理了包含克尔效应和斯塔克效应的原子与场相互作用模型。由于在其有效哈密顿中作了旋转波近似，两种效应的影响可以归结为对原子与场失谐的改变，这种失谐变化依赖于一个系统的守恒量。研究表明，克尔效应和斯塔克效应在一定条件下是等价的。研究了当场的初态为宏观可区分量子迭加态时，光子的反聚束效应。探讨了在广义的克尔介质中原子与场相互作用模型的求解。

| Abstract: | The model for describing the atom cavity field interaction including Kerr effect and Stark effect is studied. The two effects only influence the detuning which depends on a conservative operator of the system. Under certain conditions, the two effects have the same influences on the atom field interaction. The antibunching effect of the field is discussed when the initial field is in a macroscopic quantum superposition states. We also investigated how to obtain the solution of atom field interaction in a generalized Kerr medium. |
