摘要

为了方便地计算光积算子的维格纳函数及其在热环境中的耗散演化，本文引入了热纠缠态表示法来推导维格纳函数的一般演化公式，并讨论了它与韦尔对应关系。在算子的有序乘积中进行积分的方法对我们的讨论至关重要。

Wigner function of optical cumulant operator and its dissipation in thermo-entangled state representation

To conveniently calculate the Wigner function of the optical cumulant operator and its dissipation evolution in a thermal environment, in this paper, the thermo-entangled state representation is introduced to derive the general evolution formula of the Wigner function, and its relation to Weyl correspondence is also discussed. The method of integration within the ordered product of operators is essential to our discussion.
