Properties of superconductors with strong electron-phonon interaction
Abstract
A system of electrons and phonons with a strong bond (lambda is greater than 1) is considered. The temperature dependence of the upper critical field has a positive curvature. A relationship is established between the electron state density, specific heat discontinuity, lower and upper critical fields, and residual resistance.
