中文摘要：

用数值计算方法研究了与强度有关的双光子J—C模型中原子的粒子数反转特性和光子统计演化．结果表明：量子崩塌与复苏的性质只能维持很短的时间，然后将趋向混乱，且随着初始平均光子数万值的不断增加，场与原子的非线性耦合越来越强，崩塌与复苏周期越来越短．这显然跟与强度无关的双光子J—C模型中原子和光场的量子特性不同．

英文摘要：

In this paper, we study the properties of the atomic inversion and statistical evolution behavior of the mean photon number in the two-photon J-C model with intensity-dependent coupling by means of numerical method. The results show that the quantum collapse and revival properties keep a short time, and then trend to chaos in this model. When the initial mean photon number ~ increases, the nonlinear coupling between atom and field will become stronger and the period of collapse and revival will become shorter. It＇s obvious that the above results and the quantum properties in the two-photon J-C model with intensity-independent coupling are different.
