First order phase transition and tricritical point in multiband U(1) London superconductors | | Karl A. H. Sellin

10 Aug 2015 | | Abstract: | The order of the superconducting phase transition is a classical problem.
Single-component type-2 superconductors exhibit a continuous "inverted-XY"
phase transition, as was first demonstrated for U(1) lattice London
superconductors by a celebrated duality mapping with subsequent backing by
numerical simulations. Here we study this problem in multiband U(1) London
superconductors and find evidence that by contrast the model has a tricritical
point. The superconducting phase transition becomes first-order when the
Josephson length is sufficiently large compared to the magnetic field
penetration length. We present evidence that the fluctuation-induced dipolar
interaction between vortex loops makes the phase transition discontinuous. We
discuss that this mechanism is also relevant for the phase transitions in
multicomponent gauge theories with higher broken symmetry. | | Source: | arXiv, 1508.2311 | | Services: | Forum | Review | PDF | Favorites | |
