Magnetic monopoles in a charged two-condensate Bose-Einstein system
arXiv:cond-mat/0410121 · doi:10.1103/PhysRevB.70.012501
Abstract
We propose that a charged two-condensate Bose system possesses point-like topological defects which can be interpreted as magnetic monopoles. By making use of the -mapping theory, the topological charges of these magnetic monopoles can be expressed in terms of the Hopf indices and Brouwer degree of the -mapping.
