A theory of superconductivity is presented, based on the fact that the interaction between electrons resulting from virtual exchange of phonons is attractive when the energy difference between the electrons states involved is less than the phonon energy, ℏω. It is favorable to form a superconducting phase when this attractive interaction dominates the repulsive screened Coulomb interaction. The normal phase is described by the Bloch individual-particle model. The ground state of a…

The Microscopic Theory of Superconductivity-Verifications and Extensions
The microscopic theory of superconductivity was formulated in 1957 by Bardeen, Cooper, and Schrieffer. In the BCS model, the ground state of super electrons is built up by pairs kept together by an
On the theory of high Tc superconductors
An outline of the various theoretical problems is presented which arise from the unique physical properties of the new copper oxide superconductors. First, it is argued that the superconducting state
A Spin Fluctuation Model for d-Wave Superconductivity
The identification of the microscopic mechanisms responsible for superconductivity and the nature of the superconducting pairing state continues to represent one of the most exciting theoretical
Theory of superconductivity at high temperatures
Superconductivity is generally explained by an electron-lattice interaction which results in the pairing of electrons and the condensation of these pairs into a state of lower entropy. In
Electron-Phonon Interactions and Superconductivity
One of Frohlich’s major achievements was to point out the significance of the electron-phonon interaction in superconductivity, and his formulation of the problem has been the basis for nearly all subsequent theoretical developments.
A Review of Theories of Superconductivity
The first ever phenomenological theory of superconductivity was propounded by London brothers (Fritz and Heinz) by correlating the current in a superconductor with a vector potential and using
Theory of superconductivity. I. Electron-lattice interaction
The electron-lattice interaction responsrble for electrical resistivity in perfect metallic crystals is a form of JahnTeller effect. It does not occur in the Bonn-Oppenheimer (adiabatic)
Pairing in two dimensions and possible consequences for superconductivity: extension of Cooper's approach
Relation between the binding energy of a pair of electrons in Cooper's configuration and the magnitude of the attractive interaction between them is investigated theoretically for a two-dimensional

The penetration depth, λ, in superconducting tin at 0° K has been found to be capable of variation by the addition of impurity, 3% of indium causing it to be nearly doubled, although the
The electromagnetic equations of the supraconductor
Electric currents are commonly believed to persist in a supra-conductor without being maintained by an electromagnetic field. Thus the relation between the field strength E and the current density J
