Microwave conductivity of a d-wave superconductor disordered by extended impurities: a real-space renormalization group approach

Superconductivity 2009-11-10 v3

Abstract

Using a real-space renormalization group (RSRG) technique, we compute the microwave conductivity of a d-wave superconductor disordered by extended impurities. To do this, we invoke a semiclassical approximation which naturally accesses the Andreev bound states localized near each impurity. Tunneling corrections (which are captured using the RSRG) lead to a delocalization of these quasiparticles and an associated contribution to the microwave conductivity.
