Effects of disorder on the transmission of nodal fermions through a d-wave superconductor

Abstract

The bulk microwave conductivity of a dirty d-wave superconductor is known to depend sensitively on the range of the disorder potential: long-range scattering enhances the conductivity, whereas short-range scattering has no effect. Here we show that the three-terminal electrical conductance of a normal-metal-d-wave superconductor-normal-metal junction has a dual behavior: short-range scattering suppresses the conductance, whereas long-range scattering has no effect. © 2011 American Physical society.
