查询词典 topological structure

It is revealed that in the condensates, the different configurations of order parameters lead to different topological structures-velocity field vortex lines, Mermin-Ho vortex lines and monopoles, and these three topological structures can all be characterized by the Hopf indices and Brouwer degrees of φ-mapping, and their locations and motions also be rigorously determined by φ-mapping theory.
