Abstract

Vortices in spin-0 superfluids generically carry magnetic fields inside their cores, so that even neutral superfluid vortices may be thought of as magnetic flux tubes. We give a systematic analysis of this 'vortex magnetic effect' using effective field theory, clarifying earlier literature on the subject. Our analysis shows that in superfluid helium-4 the vortex magnetic effect may be large enough to be experimentally detectable.
