Vortex phases of an unconventional superconductor with two components order parameter
Abstract
We examined the single vortex structure of superconductor with the order parameter of two components by numerical calculation. Under certain conditions in the case of time-reversal preserving phase a single vortex dissociates into a pair of half-quantum vortices. We determine the phase diagram for these vortices in the space of parameters of the Ginzburg-Landau functional. A novel characteristic length which is longer than the coherence length ξ and shorter than the magnetic penetration length λLondon is introduced.
