| 摘 要： | 研究了与时间有关的非线性 J-C 模型中的原子动力学行为,讨论了原子与光场以时间脉冲的形式耦合时其脉冲宽度和腔场的平均光子数对原子动力学行为的影响。结果发现,当腔场的平均光子数一定时,随着脉冲宽度的增大原子崩塌与回复次数增多,崩塌时间和回复周期变小;而当脉冲宽度一定时,随着腔场的平均光子数的增大原子的崩塌时间和回复周期逐渐减小。

| Abstract: | The dynamic behavior of atoms in time-dependent nonlinear J-C model is studied. The influ- ence of pulse width and average photon number on dynamic behavior of atoms as the atoms are cou- pled with photon field in the form of time pulse is discussed. The result shows that when the average photon number is fixed in the field,with the increase of pulse width,the collapse and revival number are enhanced,while the time of collapse and period of revival are reduced. When the pulse width is fixed,the time of collapse and revival period are reduced gradually with the increase of pulse width in the field. |
