【 摘 要 】
By making use of the decomposition of U(1) gauge potential theory and the phi-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 phi-mapping, and the knotted solitons are described by the nontrivial Hopf invariant and the BF action, respectively.
