摘要
本文引入反常玻色子系统的相干态和新定义的分布函数,将正则密度矩阵的Bloch方程、非平衡态密度矩阵的von Neumann方程以及Heisenberg运动方程转换为可分离变量的偏微分方程,并给出了它们的形式解,还讨论了便于微扰求解的相互作用表象。
Introducing the coherent state for abnormal boson systems and a newly defined distribution ??function, the Bloch equation for canonical desity matrix, the yon Neumann equation for nonequilibrium density matrix and the Heisenberg equation of motion are converted into partial differential equations of the type of separating variables respectively. Formal solutions of them are presented. Furthermore, the interaction representation for the perturbational expansion has been discussed.
