Abstract

Using the field theory method and coherent spin state approach, we investigate properties of magnetic solitons in spacetime while focussing on 1D kinks, 2D and 3D skyrmions. We also study the case of a rigid skyrmion dissolved in a magnetic background induced by the electronic spins; and derive the effective rigid skyrmion equation of motion. We investigate as well the interaction between an electron and a 3D skyrmion.
