Short-range interacting skyrmion charges in the long-range interacting skyrmion lattice

A topological excitation-skyrmion in p-wave superconductors is studied in the context of Landau–Ginzburg–Wilson (LGW) theory. Interaction between skyrmion charge densities is shown to be short ranged from a derived effective field model. The computed energy per single skyrmion of skyrmion lattice suggests a long ranged lattice interaction.
