Josephson interference in a Superconducting Quantum Int- ference Device (SQUID) shows that the centers of masses (CM) of pairons move as bosons with a linear dispersion relation. Based on this evidence we develop a theory of superconductivity in conventional and mate- als from a unified point of view. Following Bardeen, Cooper and Schrieffer (BCS) we regard the phonon exchange attraction as the cause of superc- ductivity. For cuprate superconductors, however, we take account of both optical- and acoustic-phonon exchange. BCS started with a Hamiltonian containing 'electron' and 'hole' kinetic energies and a pairing interaction with the phonon variables eliminated. These 'electrons' and 'holes' were introduced formally in terms of a free-electron model, which we consider unsatisfactory. We define 'electrons' and 'holes' in terms of the cur- tures of the Fermi surface. 'Electrons' (1) and 'holes' (2) are different and so they are assigned with different effective masses: Blatt, Schafroth and Butler proposed to explain superconductivity in terms of a Bose-Einstein Condensation (BEC) of electron pairs, each having mass M and a size. The system of free massive bosons, having a quadratic dispersion relation: and moving in three dimensions (3D) undergoes a BEC transition at where is the pair density. 404 pp. Englisch, Books<
