Description
Recently there was much interest in superconducting states
which break time reversal symmetry.
Examples being p+ip superconductors or three band
superconductors with frustrated interband couplings.
We will discuss that when this symmetry is broken the system
posses stable or, in certain cases metastable skyrmions
characterized by CP1, or in case of three band superconductors
CP2 symmetry. These Skyrmions can be viewed as stable
configuration of spatially separated fractional vorteces.
