Topological and Hopf charges of a twisted Skyrmion string
Abstract
We study nonlinear sigma model, especially Skyrme model with twist (twisted Skyrmion string) where twist term mkz is indicated in vortex solution. We study topological and Hopf charges of a twisted Skyrmion string. We show that the Hopf charge is exist in our twisting solutions like the twisted Skyrmion string.
