摘要
We find that there exists an elementary topological current in Bose-Einstein condensation. Based on the phi-mapping topological current theory, the implicit function theorem and the Taylor expansion, the topological structure of vortex lines is detailed in the neighborhoods of the bifurcation points of the condensate wave function.
