Husimi算符与热真空态的Husimi分布函数

Husimi Operator and Husimi distribution of Thermal Vacuum States

利用Husim i算符作为一个纯态密度算符的事实,我们导出了热场态的Husim i函数及其边缘分布。通过绘制相空间的Husim i分布图形,我们简要讨论了高斯展宽参数以及热真空态的温度对Husim i函数的影响。

By using the fact that Husimi operator can be considered as a density operator of pure state, we derive the Husimi function of thermal vacuum states and other marginal functitns. By plotting the distribution graphs of Husimi function in phase space, we briefly discuss Gaussian broaden parameters and the effect of thermal vacuum state the eanprature to Husimi distribution function.
