利用平均场理论研究了自旋为1的玻色-爱因斯坦凝聚体铁磁态中skyrmion的性质，证明了skyrmion的大小与其愈合长度的数量级有关.结果表明，当两个自旋方向相反的skyrmions的间距较大时，它们之间的相互作用是吸引的，遵循一个独特的幂律行为，幂为-7/2。
We investigate the properties of skyrmion in the ferromagnetic state of spin-1 Bose-Einstein condensates by means of the mean-field theory and show that the size of a skyrmion is fixed to the order of the healing length. It is shown that the interaction between two skyrmions with oppositely rotating spin textures is attractive when their separation is large, following a unique power-law behavior with a power of -7/2.
