Effects of anisotropic impurity scattering on thermal conductivity and thermoelectric effect in unconventional superconductors

We report analytic and numerical results for the thermal conductivity and thermoelectric effect in unconventional superconductors with a dilute random distribution of impurities. We present new results for the effects of anisotropic impurity scattering. For low temperatures we present analytic results for the universal limit asymptotics and the $T^3$ corrections. Only the $T\rightarrow 0$ value of the thermal conductivity remains universal (independent of the impurity scattering potential). All other quantities depend on the phase shifts and vertex corrections.
