多级微扰体系的格林函数法

Method of Green's Function for Systems under Multi-order Perturbation

本文表明,对具有任意多级微扰作用的量子体系,应用定态问题的格林函数法,可方便地得到无简并量子体系状态与能级各阶修正公式的普遍形式。

The result of this paper has shown that the universal correction for mula forms on every order of state and energy level of non-degenerate quantum system, for quantum system with any order perturbation, can be got with method of Green's function forstationary state problems.
