    Abstract

    We report the result of calculation of the quasiparticle thermal conductivity κ xx (∇ T ⊥ B) in the vortex state of a two-dimensional superconductor. We compute κ xx for both s-wave and d-wave superconductors, taking account of the spatial dependence of normal Green's function g, which is neglected in the previous studies using the Brandt-Pesch-Tewordt (BPT) method. Our results indicate that κ xx based on the BPT method is slightly underestimated due to its incoherent spatial averaging procedure.
