| 摘 要： | 使用幺正转化方法对Ee系统的绝热势能进行计算,得到势能面的最低槽,对二次耦合项所引起的绝热势能面的变形做初步探讨;利用Mathematica软件对该系统能量和线性耦合强度的函数关系做数学模拟.与求解繁琐的声子态方法相比,该方法不仅减少了计算量,而且更能体现出相关参量的物理含义.

| Abstract: | The adiabatic potentials of the Ee system was calculated using unitary transformation method and the lowest trough of adiabatic potential energy surface was obtained.The distortion of the adiabatic potential energy surface caused by the quadratic coupling term was also initially studied;Moreover,the function relation between the energy of system and linear coupling intensity was mathematically simulated using Mathematica software.Comparing with the methods of calculating massive phonons states,this method in this article not only reduced computations quantity,but also was able to manifest physical mechanism of the relevant constants. |
