Current-loops, phase transitions, and the Higgs mechanism in Josephson-coupled multi-component superconductors
Peder N. Galteland, Asle Sudbø
The -component London superconductor is expressed in terms of integer-valued supercurrents. We show that the inclusion of inter-band Josephson couplings introduc…
Competing interactions in population-imbalanced two-component Bose-Einstein condensates
Peder N. Galteland, Asle Sudbø
We consider a two-component Bose-Einstein condensate with and without synthetic "spin-orbit" interactions in two dimensions. Density- and phase-fluctuations of the condensate are i…
Immiscibile two-component Bose Einstein condensates beyond mean-field approximation: phase transitions and rotational response
Peder N. Galteland, Egor Babaev, Asle Sudbø
We consider a two-component immiscible Bose-Einstein condensate with dominating intra-species repulsive density-density interactions. In the ground-state phase of such a system onl…
Fluctuation effects in rotating Bose-Einstein condensates with broken and symmetries in the presence of intercomponent density-density interactions
Peder N. Galteland, Egor Babaev, Asle Sudbø
Thermal fluctuations and melting transitions for rotating single-component superfluids have been intensively studied and are well understood. In contrast, the thermal effects on vo…
