By making use of Duan-Ge's decomposition theory of gauge potential and the topological current theory proposed by Prof. Duan Yi-Shi, we study a two-component superfluid Bose condensed system, which is supposed to be ...

Based on Duan's topological current theory,we propose a novel approach to study the topological properties of topological defects in a two-dimensional complex vector order parameter system.This method shows explicitl...

An unconventional integer quantum Hall regime was found in magnetic semiconductor-superconductor hybrids. By making use of the decomposition of the gauge potential on a U(1) principal fibre bundle over k-space, we s...

This paper studies the topological properties of knotted solitons in the (3 +1)-dimensional Aratyn-Ferreira- Zimerman (AFZ) model. Topologically, these solitons are characterized by the Hopf invariant I, which is...
