Abstract

We review some of the topological properties of Fermi superfluids, in particular the persistent currents in superfluid 3He. We show that the topological charge formalism developed by Garg et al. is related to the chiral anomaly viewpoint of Volovik and co-workers through the Callan-Harvey effect. We stress that the question of the existence of a "twist" term in the current induced by a texture is a history-dependent phenomenon which depends on how the textures are envisaged as being created.
