摘要
通过对含s参数广义Wigner算符进行正规、反正规编序,导出一组新的算符微分关系式,进而提出统一推导量子相空间三种分布函数的Fokker-Planck方程的有效方法.
A new set of differential relationship of operators are obtained by normally and anti-normally ordering the generalized Wigner operator with s parameter,and then an unified method is proposed to derive the Fokker-Planck equations for distribution functions of three types in quantum phase space.
