Anyonic Bogomolʼnyi solitons in a gauged O(3) Σ model

초록

We introduce the self-dual Abelian gauged O(3) Σ models where the Maxwell and Chern-Simons terms constitute the kinetic term for the gauge field. These models have quite rich structures and various limits. Our models are found to exhibit both symmetric and broken phases of the gauge group. We discuss the pure Chern-Simons limit in some detail and study rotationally symmetric solitons. © 1996 The American Physical Society.
