A Necklace of Fractional Vortices

Caption

A route to a time-reversal symmetry-broken state for d-wave superconductors is shown to occur via the formation of a necklace of fractional vortices around the perimeter of the material, where neighboring vortices have opposite current circulation. This vortex pattern is a result of a spectral rearrangement of current-carrying states near the edges.
