Knotted Topological Phase Singularities of Electromagnetic Field
Knotted Topological Phase Singularities of Electromagnetic Field
In this paper, knotted objects (RS vortices) in the theory of topological phase singularity in electromagnetic field have been investigated in details. By using the $\phi$-mapping topological current theory proposed by Prof. Duan, we rewrite the topological current form of RS vortices and use this topological current we reveal that …
