G.V. Vlasov (Landau/Moscow Aviation)
TL;DR
This paper develops a theoretical framework for sound propagation in relativistic superfluids containing quantum vortices, introducing new modes absent in non-relativistic counterparts.
Contribution
It presents a novel theory of sound in relativistic superfluids with vortices, including a vortex fluid model and discovery of new sound modes.
Findings
Identification of new sound modes in relativistic superfluids
Development of a vortex fluid model for relativistic vortices
Comparison showing these modes are absent in non-relativistic superfluids
Abstract
We develope a theory of sound in a relativistic superfluid with quantum vortices. The vortices are presented by vortex fluid. For a particular separable model we find new modes of which a non-relativistic superfluid is deprived.
