11 Jul 2013 | Abstract: | Rather generically, multicomponent superconductors and superfluids have
intercomponent current-current interaction. This applies to wide range of
physical systems from mixtures of hadronic superfluids in neutron stars,
ultracold atoms to p-wave superconductors. Here we discuss how this kind of
interaction affects magnetic response of superconductors. Going beyond the
frequently used London limit, we show that in superconductors with
substantially strong intercomponent drag interaction, the topological defects
which form in external field are Skyrmions. We study their properties and show
that they can be distinguished from ordinary vortices by a very characteristic
magnetization process. | Source: | arXiv, 1307.3211 | Services: | Forum | Review | PDF | Favorites |
