Zusammenfassung
Observability of fractional vortices and Skyrmions in superconductors is a
question which attracted recently increasing attention. Under the most common
conditions, fractional vortices are not thermodynamically stable in bulk
samples. Here we show that in chiral p-wave superconductors, there is a regime
where, in contrast lattices of integer flux vortices are not thermodynamically
stable. Instead Skyrmions and fractional vortices are the topological defects
produced by an applied external field.
