Abstract
We show that scattering processes in anisotropic superconductors have some unexpected asymmetries when the normal-state phase shift is neither small nor resonant. The scattering rate is not symmetric about the Fermi surface, which gives rise to large thermoelectric effects. For states with gaps that have nontrivial phase variations over the Fermi surface, certain components of transport coefficient tensors can be finite even though they vanish in the normal state.
