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.
