't Hooft-Polyakov Monopoles in an Antiferromagnetic Bose-Einstein Condensate
arXiv:cond-mat/0103194 · doi:10.1103/PhysRevLett.87.120407
Abstract
We show that an antiferromagnetic spin-1 Bose-Einstein condensate, which can for instance be created with Na-23 atoms in an optical trap, has not only singular line-like vortex excitations, but also allows for singular point-like topological excitations, i.e., 't Hooft-Polyakov monopoles. We discuss the static and dynamic properties ofthese monopoles.
