摘要: The basic perturbation theoretic method for dealing with non-equilibrium quantum statistical mechanical problems has been known years. theory discussed here evolved from the work of Schwinger and was developed further by Kadanoff Baym1. In fact virtually all is contained in Kadanoff’s Baym’s book. Essentially same independently Keldysh2 who even anticipates a rather useful addendum Craig3.
