Quasiparticle localization in dirty high-Tc superconductors

Abstract:  A general low temperature theory of the effects of disorder on the quasiparticles in the high-Tc superconductors is presented. It is argued that the superconductor represents a new context for localization phenomena. Interesting differences with normal metals are pointed out, and analyzed. As an upshot, a novel spin phase - the "spin metal" - is shown to be naturally realizable in the high-Tc superconductors.
