Skyrmions in spinor bose-einstein condensates

Abstract

As a physical medium, cold atoms are wildly different from solid-state magnetic materials. Yet, some aspects of cold atom physics are subject to the same homotopy analysis we performed in Chap. 2, and relevant topological excitations can be classified accordingly. Indeed, vortices, skyrmions, and other interesting exotic topological excitations are possible states in spinor condensates, which are the quantum gases made up of atoms with spin.
