Thermal conductivity in the vortex state of d-wave superconductors

Abstract

We present the results of a microscopic calculation of the longitudinal thermal conductivity of quasiparticles, ${\kappa }_{xx}$, in a 2D d-wave superconductor in the vortex state. Our approach takes into account both impurity scattering and a contribution to the thermal transport lifetime due to the scattering of quasiparticles off of vortices. We compare the results with the experimental measurements on high-T${}_c$ cuprates and organic superconductors.
