Description

We show that vortices in scalar superfluids can carry magnetic fields inside their cores when the condensing particle is composed of excitations that are oppositely charged and are not degenerate. We estimate the size of this magnetic field using effective field theory and illustrate how such an effect can arise from the underlying microphysics. Our findings may have observational consequences for helium superfluid as well as other BEC.
