FINITE TEMPERATURE THEORY FOR THE ATTENUATION OF QUASI-PARTICLE EXCITATIONS IN REAL METALS

Abstract

The finite temperature generalization of the Quinn, Adler theory for the decay rate of electronic excitations in a normal Fermion system is presented. The theory is developed in terms of quasi-particle parameters and without restriction to a particular approximation, such as RPA, for the dielectric response of the system. The relations derived are pertinent to the lifetime problem in real solids; in particular, local field effects are rigorously taken into account.
