Abstract

We discuss the current-carrying state in a polar-phase superconductor at zero temperature. This phase has a line of nodes on the Fermi surface, and its properties are quite anisotropic. We compute the relation between J and vs both for a pure metal and for one with impurities. This allows us to find the critical current for a variety of situations. We also consider the density of states in the presence of superflow.
