Exact Self-dual Soliton Solutions in a Gauged O(3) Sigma Model with Anomalous Magnetic Moment Interaction
Ghosh, Pijush K.
Original · EN
It is shown that a gauged nonlinear O(3) sigma model with anomalous magnetic moment interaction in 2+1 dimensions is exactly integrable for static, self-dual field configurations. The matter fields are exactly equivalent to those of the usual ungauged nonlinear O(3) sigma model. These static soliton solutions can be mapped into an Abelian purely magnetic vortex solutions through a suitable reduction of the non-Abelian gauge group. A relativistic Abelian model in 2+1 dimensions is also presented where these purely magnetic vortices can be realized.
