非相对论BUU方程

NON-RELATIVISTIC BUU EQUATION

基于闭合时间格林函数技术,在H-F和Born近似下,完成了一级和二级微扰计算,得到了不同微扰下的自能和格林函数运动方程,并分别在局域和非局域近似下,得到了单粒子格林函数的Wigner函数随时间变化的Boltzmann-Uehling-Uhlenbeck(BUU)方程和它的扩展形式.并对导出BUU方程的近似做了总结和讨论.

The Boltzmann-Uehlig-Uhlenbeck (BUU) equation, which is the time evolution of the wigner function of the single particle Green's function, is derived by using the closed-time Green's function approach. The quantum mechanical approximation in deriving the BUU equation is discussed.
