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.
