K光子Jaynes-Cummings模型中自发辐射的Berry相位的零级近似

Zero-Order Approximation of Berry′s Phase of Spontaneous Emission in K-Photon Jaynes-Cummings Model

介绍了Ｂｅｒｒｙ相位，计算了Ｋ光子Ｊ－Ｃ模型中自发辐射的Ｂｅｒｒｙ相位的零级近似，指出了如果一个量子力学系统的哈密顿量的本征态由有限个粒子数态迭加而成，其Ｂｅｒｒｙ相位或Ｂｅｒｒｙ相位的零级近似是其在参数空间上闭合曲线面积的负二倍。

Introduces berry′s phase and Calculates Zero-order approximation of Berry′s phase of spontaneous in K-photon Jaynes-Cummings model.The result shows that,if the eigenstate of the Hamittonian of quantum mechanical system was wuperposed by a number of quantum states,it′s Berry′s phase or zero-oder approximation of Berry′s phase would be negative two times of the area of the closed cure in the parameter space.
