Supercurrents in the A1 Phase of 3He

We discuss how Fermi liquid interactions renormalize the supercurrents that flow in the A1 phase of superfluid 3He. An interesting point which emerges from the calculation is that the unpaired spin population does not participate in superflow, despite superficial appearances to the contrary. We consider both the usual version of Fermi liquid theory and a generalized version appropriate in high magnetic fields
