Abstract

The physical mechanism by which a pair of electrons just above the Fermi energy forms a bound state is physically analyzed and explicit quantitative results for the binding energy and the critical superconducting temperature are obtained. The possibility of Cooper pair formation forces a reorganization of the Fermi sea along the line proposed by Bardeen–Cooper–Schrieffer. This leads to the self-consistent BCS theory, which is capable of obtaining the thermodynamic, transport, and other superconducting properties in terms of the dimensionless phonon attractions, λ, and the dimensionless screened Coulomb repulsion, μ*. The generalization of the DFT to the superconducting state (aiming at material specific ab initio calculations) is outlined. The DC and AC Josephson effects as well as the superconducting quantum interference phenomenon are presented.
