Skyrmion Excitation in Two-Dimensional Spinor Bose-Einstein Condensate
arXiv:cond-mat/0210397 · doi:10.1103/PhysRevA.68.043602
Abstract
We study the properties of coreless vortices(skyrmion) in spinor Bose-Einstein condensate. We find that this excitation is always energetically unstable, it always decays to an uniform spin texture. We obtain the skyrmion energy as a function of its size and position, a key quantity in understanding the decay process. We also point out that the decay rate of a skyrmion with high winding number will be slower. The interaction between skyrmions and other excitation modes are also discussed.
