Microwave conductivity due to impurity scattering in a d-wave superconductor
Abstract
The self-consistent t-matrix approximation for impurity scattering in unconventional superconductors is used to interpret recent measurements of the temperature and frequency dependence of the microwave conductivity of YBa2Cu3O6.993 crystals below 20 K. In this theory, the conductivity is expressed in terms of a frequency dependent single particle self-energy, determined by the impurity scattering phase shift which is small for weak (Born) …
