Topological Excitation in an Antiferromagnetic Bose-Einstein Condensate

Condensed Matter 2009-11-10 v3

Abstract

Two kinds of topological excitations, skyrmions and monopoles, are studied. It is revealed that these two types of excitations originate from different order parameter fields that reflect different spatial distributions of the Neel vector. Critical phenomena of the generation and annihilation of skyrmion-antiskyrmion pairs are also discussed.
