Thermal Effects on the Green’s Function
Up to now we have avoided any discussion of thermal effects upon the interacting system apart from drawing attention, in Chap. 5, to the similarity between the existence of inexact states in interacting quantum mechanics and the equipartition theorem in statistical mechanics. In fact, quantum statistical mechanics is based upon the same framework as classical statistical mechanics. For this reason we will not try to develop a detailed theory here but simply cover the ground sufficiently to derive the required properties.
