Phys. Rev. A 75, 043601 (2007) [8 pages]Solitons in a trapped spin-1 atomic condensateReceived 29 April 2006; published 2 April 2007 We numerically investigate a particular type of spin soliton inside a trapped atomic spin-1 Bose-Einstein condensate with ferromagnetic interactions. Within the mean-field theory approximation, our study of the solitonic dynamics shows that the solitonic wave function, its center-of-mass motion, and the local spin evolutions are stable and are intimately related to the domain structures studied recently in spin-1 87Rb condensates. We discuss a rotating reference frame wherein the dynamics of the solitonic local spatial spin distribution becomes time independent. © 2007 The American Physical Society URL:
