我们研究了具有自旋自由度的超冷气态原子玻色-爱因斯坦凝聚中的物质波孤子，并提出了一类基于逆散射方法的精确解。单孤子解根据自旋态进行分类。我们分析了相同或不同自旋状态的孤子之间的碰撞效应，这揭示了一个非常有趣的可能性：我们可以通过控制碰撞孤子的参数来操纵自旋动力学。
We study matter-wave solitons in Bose-Einstein condensates of ultracold gaseous atoms with spin degrees of freedom and present a class of exact solutions based on the inverse scattering method. The one-soliton solutions are classified with respect to the spin states. We analyze collisional effects between solitons in the same or different spin state(s), which reveals a very interesting possibility: we can manipulate the spin dynamics by controlling the parameters of colliding solitons.
