Many-Body Operator Green Functions

  • Jonas Fransson
Part of the Lecture Notes in Physics book series (LNP, volume 809)

Abstract

The formalism is extended to propagators, Green functions, in equilibrium and non-equilibrium. The contoured ordered Green functions, used in non-equilibrium, are introduced and we discuss the analytical continuation to real time correlation functions.
