SUPERCONDUCTOR GLASS PHASE IN STRONGLY DISORDERED BULK SYSTEMS

The superconducting behaviour of highly disordered bulk electronic sys tems close to the metal-insulator transition (MIT) is considered. It i s argued that these systems are frustrated even in the absence of a ma gnetic field. If disorder fluctuations are larger than some critical v alue a superconductor glass phase is predicted. Technically the result s are based on Thouless-Anderson-Palmer-like mean-field equations that are derived to describe the proposed glass transition.
