Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid
Flux tubes and the type-I/type-II transition in a superconductor coupled to a superfluid
We analyze magnetic-flux tubes at zero temperature in a superconductor that is coupled to a superfluid via both density and gradient (``entrainment'') interactions. The example we have in mind is high-density nuclear matter, which is a proton superconductor and a neutron superfluid, but our treatment is general and simple, modeling …
