摘要: 应用代数动力学规范变换方法和相干态平均的方法,求解外场驱动下含时变频谐振子系统的时间演化算符,比较了两种方法所得的结果.研究结果表明,两种方法所得结果一致.

关键词: 代数动力学规范变换, 含时谐振子系统, 时间演化算符

Abstract: The time evolution operator is obtained by using the gauge transform of algebra dynamics and the expectation of coherent state for the external driven oscillator system.It is shown that the results of two methods are the same.

Key words: gauge transform of algebra dynamics, timedependent oscillator system, time evolution operator
