โœฆ Synopsis


A detailed discussion of the relationships following from time reversal invariance or covariance of many-body theories is given. The discussion includes equilibrium and nonequilibrium Keldysh Green functions. It is shown that self-consistent RPA approximations conserve the above deduced relationships. 1994 Academic Press, Inc.

The principles of an efficient, fast algorithm for the calculation of diagrams appearing in Green function and many-body perturbation methods are discussed and timing examples are given. Within the suggested algorithm, the third order-diagrams required in the Green function approach are evaluated by
