Elasticity and melting of skyrmion flux lattices in p-wave superconductors

We analytically calculate the energy, magnetization curves (B(H)), and elasticity of skyrmion flux lattices in p-wave superconductors near the lower critical field H_c1, and use these results with the Lindemann criterion to predict their melting curve. In striking contrast to vortex flux lattices, which always melt at an external field H > H_c1, skyrmion flux lattices never melt near H_c1. This provides a simple and unambiguous test for the presence of skyrmions.
