ManyBody Theory of a Localized Phonon in AN Electron Gas.
Abstract
The many body dynamic interaction of an elastic impurity with the electrons of a simple metal is considered. The threedimensional problem is approximated by three independent onedimensional problems each of which is then given an essentially exact solution at low temperatures. This is accomplished through the use of the Tomonaga  Luttinger density fluctuation description of the electron gas. The many body effects of the impurity on thermodynamic properties, Cooperpair formation, the electronic density of states, and the local magnetic susceptibility are discussed. Also included is an analysis of the palladium/hydrogendeuterium system in the light of this model. It is found that the model is able to account for the inverse isotope effect.
