Generating, dragging, and releasing dark solitons in elongated Bose-Einstein condensates
Generating, dragging, and releasing dark solitons in elongated Bose-Einstein condensates
We theoretically analyze quasi-one-dimensional Bose-Einstein condensates under the influence of a harmonic trap and a narrow potential defect that moves through the atomic cloud. Performing simulations on the mean field level, we explore a robust mechanism in which a single dark soliton is nucleated and immediately pinned by the moving …
