Dissipative superfluid relativistic magnetohydrodynamics of a multicomponent fluid: The combined effect of particle diffusion and vortices

Abstract

The authors formulate dissipative magnetohydrodynamic equations for finite temperature superfluid and superconducting mixtures, accounting for particle diffusion and the possible presence of vortices. They relate phenomenological transport coefficients to mutual friction and momentum transfer rates of the microscopic theory and suggest that this will find wide application in the study of neutron stars, particularly their magnetothermal evolution as well as their oscillations.
