Renormalization of thermal conductivity of disordered d-wave superconductors by impurity-induced local moments

Abstract

The low-temperature thermal conductivity κ0/T of d-wave superconductors is generally thought to attain a “universal” value independent of disorder at sufficiently low temperatures, providing an important measure of the magnitude of the gap slope near its nodes. We discuss situations in which this inference can break down because of competing order, and… (More)
