TL;DR
This paper demonstrates that vortices in spin-0 superfluids, such as Helium-4, inherently carry magnetic flux within their cores, with potential for experimental detection, using a systematic effective field theory approach.
Contribution
It provides a comprehensive effective field theory analysis of vortex magnetic effects in spin-0 superfluids, clarifying previous ambiguities and highlighting experimental detectability.
Findings
Vortices in spin-0 superfluids carry magnetic flux.
The magnetic effect may be detectable in Helium-4.
Systematic EFT analysis clarifies prior literature.
Abstract
Vortices in spin- 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- the vortex magnetic effect may be large enough to be experimentally detectable.
