Topological solitons stabilized by a background gauge field and soliton-anti-soliton asymmetry

Abstract We study topological lumps supported by the second homotopy group π 2(S 2) ⋍ ℤ in a gauged O(3) model without any potential term coupled with a (non)dynamical U(1) gauge field. It is known that gauged-lumps are stable with an easy-plane potential term but are unstable to expand if the model...
