摘要
本文证明，应用能量算符而不是Ｈａｍｉｌｔｏｎｉａｎ来定义量子态的位相，Ｂｅｒｒｙ位相和动力学位相都是规范不变的。作为例子，我们重新考查了广义含时谐振子绝热循回演化的量子态位相。结果表明，规范不变的Ｂｅｒｒｙ位相为零，而系统演化的几何特性体现在其动力学位相中。
The gauge invariant of Berry's phase and dynamical phase is derived by mean of energy operator instead of Hamiltonian. As an example,we have discussed the quantum state phasese of the time-dependent generalized haromic oscillator evolution circuit and Adiabatic.It is shown that the gauge invariant Berry's phase is zero and the geometric character of quantum state is expressed in the dynamical phase.
