具有拓扑位错的光晶格中的物质波孤子控制

Matter-wave soliton control in optical lattices with topological dislocations

Yaroslav V. Kartashov, Lluis Torner

摘要:

讨论了在由具有拓扑波前位错的光束干涉图样构成的光晶格通道中引导和传输物质波孤子的概念。在位错周围发生的局部晶格畸变导致孤子沿着可重构路径移动,这种现象可以用于玻色-爱因斯坦凝聚体的受控全光学操纵。多个位错形成陷阱,可以捕获和保持运动孤子。

英文摘要:

We address the concept of guiding and transporting matter-wave solitons along the channels of optical lattices made by interference patterns of beams containing topological wavefront dislocations. The local lattice distortions that occur around the dislocations cause solitons to move along reconfigurable paths, a phenomenon that may be used for controlled all-optical manipulation of Bose-Einstein condensates. Multiple dislocations form traps that can capture and hold moving solitons.
