Superconductivity From Confinement of Singlets in Metal Oxides
Abstract
The Yang-Mills description of phonons and the consequent structure of electron liquids in strongly anharmonic crystals such as metal oxides is shown to yield an attractive electron-phonon interaction, and thus an instability towards the formation of bound states, which can condense to form a superconductor. This mechanism differs significantly from the pairing mechanism of conventional superconductivity: the ground state from which superconductivity emerges is a many-body state of paired electrons and holes which is not amenable to a quasiparticle description, and whose properties are similar to those seen in the Cuprate high temperature superconductors. Confinement arises because the electron liquid structure acts as a source for Yang-Mills bosons, and not the traditional longitudinal density waves of BCS pairing.
