论文摘要
超速气体为研究孤子动力和碰撞提供了前所未有的控制水平。我们提出了一种确定性准备的方案，以在玻色子凝结物中制备三组分孤子。我们的方法基于局部自旋旋转，同时构成合适的相位和密度分布。这使我们能够观察到矢量自由程度的碰撞特性，这是出于新兴多组分孤子的连贯性而自然产生的。我们发现，准二维系统中的孤子特性由可集成的排斥三成分Manakov模型定量描述。
Ultracold gases provide an unprecedented level of control for the investigation of soliton dynamics and collisions. We present a scheme for deterministically preparing pairs of three-component solitons in a Bose-Einstein condensate. Our method is based on local spin rotations which simultaneously imprint suitable phase and density distributions. This enables us to observe striking collisional properties of the vector degree of freedom which naturally arises for the coherent nature of the emerging multi-component solitons. We find that the solitonic properties in the quasi-one-dimensional system are quantitatively described by the integrable repulsive three-component Manakov model.
