ALEXANDROV, A.S., 1999. Vortex in the charged Bose liquid. Physical Review B, 60(21), pp 14573–14576
Equations describing a single vortex in the charged Bose liquid at zero temperature are derived. The zero-temperature coherence length, magnetic-field penetration depth, vortex structure and energy, and lower critical field are calculated. The vortex differs from that in type-II BCS superconductors or in neutral superfluids. Its core is charged, and there is an electric field inside the core.
