Theory of disordered unconventional superconductors

In contrast to conventional s wave superconductivity unconventional e g p or d wave su perconductivity is strongly suppressed even by relatively weak disorder Upon approaching the superconductor metal transition the order parameter amplitude becomes increasingly inhomoge neous leading to e ective granularity and a phase ordering transition described by the Mattis model of spin glasses One consequence of this is that at low enough temperatures between the clean un conventional
