孤子的拓扑拖曳

Topological dragging of solitons

Yaroslav V. Kartashov, Victor A. Vysloukh, Lluis Torner

摘要:

提出了具有拓扑位错的光晶格支撑的孤子的性质,指出孤子在位错周围受到吸引力和排斥力。合适的位错的安排,甚至发现形成孤子陷阱,和这样的孤子的性质被证明是至关重要的依赖于陷阱的拓扑结构。发现的现象为孤子控制和操纵开辟了新的概念,例如,在圆盘状的玻色-爱因斯坦凝聚体中。

英文摘要:

We put forward properties of solitons supported by optical lattices featuring topological dislocations, and show that solitons experience attractive and repulsive forces around the dislocations. Suitable arrangements of dislocations are even found to form soliton traps, and the properties of such solitons are shown to crucially depend on the trap topology. The uncovered phenomenon opens a new concept for soliton control and manipulation, e.g., in disk-shaped Bose-Einstein condensates.
