Magnetic Skyrmions at Critical Coupling [PDF]
Communications in Mathematical Physics, 2020 AbstractWe introduce a family of models for magnetic skyrmions in the plane for which infinitely many solutions can be given explicitly. The energy defining the models is bounded below by a linear combination of degree and total vortex strength, and the configurations attaining the bound satisfy a first order Bogomol’nyi equation.
