我们发现，自旋为1的玻色-爱因斯坦凝聚体与铁磁相互作用自发地产生一个拓扑自旋纹理，其中的m = +/- 1组件的磁子级形成相反的循环涡旋。这种现象源于铁磁相互作用和自旋守恒之间的相互作用。
We show that a spin-1 Bose-Einstein condensate with ferromagnetic interactions spontaneously generates a topological spin texture, in which the m = +/- 1 components of the magnetic sublevels form vortices with opposite circulations. This phenomenon originates from an interplay between ferromagnetic interactions and spin conservation.
