Half-skyrmion in spinor bose-einstein condensates

摘要

In this paper, we present exact solutions to the F = 1 spinor Bose-Einstein condensates with only spin-independent energy by adopting a method of separating the variables, which exhibit nontrivial topology. These solutions can form solitonic fractional vortex and solitonic half-skyrmion with a Q = 1/2 topological charge in the two-dimensional system. We further address a three-dimensional prototype solution.
