12 May 2016 | | Abstract: | We investigate the magnetization processes of a standard Ginzburg-Landau
model for chiral $p$-wave superconducting states in an applied magnetic field.
We find that the phase diagram is dominated by triangular lattices of doubly
quantized vortices. Only in the close vicinity of the upper critical field, the
lattice transforms into a lattice of single-quanta vortices. The degeneracy
between states with opposite chirality is broken in a nonzero field. If the
magnetization starts with an energetically unfavorable chirality, the process
of chirality-inversion induced by the external magnetic field results in a
formation of a sequence of metastable states with characteristic magnetic
signatures that can be probed by standard experimental techniques. | | Source: | arXiv, 1605.3946 | | Services: | Forum | Review | PDF | Favorites | |
