谐振子任意次幂坐标算符矩阵元的一种计算方法

A calculation method of coordinate operator matrix element of harmonic oscillator

利用相干态和正规乘积对谐振子任意次幂坐标算符X1矩阵元进行了讨论,导出了计算X1矩阵元的一般公式,其结果与《大学物理》发表的两篇文章一致,为处理谐振子的微扰问题提供了一种新的方法.

Matrix element of coordinate operator X1 of harmonic oscillator is discussed by using coherent state and normal product, the general formula calculating matrix element of X1 is obtained, the result is the same to the two articles in 《College Physics》.
