Magnetic Vortices in a Gauged O(3) Sigma Model with Symmetry Breaking Self-Interaction
arXiv:hep-th/9705196 · doi:10.1103/PhysRevD.58.105025
Abstract
We consider a (2+1) dimensional nonlinear O(3) sigma model with its U(1) subgroup gauged along with the inclusion of a self-interaction having symmetry breaking minima.The gauge field dynamics is governed by the Maxwell term.The model is shown to support topologically stable purely magnetic self-dual vortices.
