摘要
主要是研究含时线性谐振子系统的量子解问题.首先运用李代数方法得到含时线性谐振子系统的密度算符随时间演化的量子精确解,然后对得到的解析式进行了验证和分析.结果显示,我们得到的含时谐振子系统密度算符的解析解能准确的描述含时谐振子系统密度算符随时间的演化.
In the paper, the time dependent linear harmonic oscillator system has been studied. Firstly, the exact quan tum solution of density operator of the time--dependent linear harmonic oscillator system has been obtained by using I.ie algebra method. Secondly, the analytic expression has been tested and discussed and it shows that the analytic expression of density operator can well describe the process for time evolution of density operator.
