USE OF THERMAL GREEN'S FUNCTION FOR THE ELECTRON-ION INTERACTION IN SUPERCONDUCTORS
Abstract
Starting with the Bardeen and Pines Hamiltonian for metals, the screening effect of the electronion interaction and the change of frequency of the ionic oscillation in superconductors have been considered by introducing a Hartree field in place of the pairing interaction of Cooper. Use is made of the method of thermal Green's functions which affords us analytically tractable results. A method has been proposed to determine a number of parameters involved in the Hartree field in a self-consistent way. (Author)
