Description

By making use of the decomposition of U(1) gauge potential theory and the φ-mapping method, we propose that a charged two-condensate Bose system possesses vortex lines and two classes of knotted solitons. The topological charges of the vortex lines are characterized by the Hopf indices and the Brower degrees of φ-mapping, and the knotted solitons are described by the nontrivial Hopf invariant and the BF action, respectively
