Abstract

We show that in anisotropic superconductors in which impurity scattering is the dominant relaxation process at low temperatures, the viscosity and ultrasonic attenuation in the hydrodynamic regime, when calculated in the Born approximation, tend to constant values while the thermal conductivity, κ, varies as T. These results are in conflict with experiment. We show that if multiple-scattering effects are taken into account, the ultrasonic attenuation and κ/T fall with decreasing temperature.
