Soliton Dynamics in the Collisions of Bose-Einstein Condensates: An Analog of the Josephson Effect

Abstract
The usual mean-field description of trapped atomic Bose-Einstein condensates predicts the existence of solitons in one-dimensional and quasi-one dimensional confinement. If the net atomic pair interaction is attractive, these solitons appear as coherently propagating matterwavepackets; if it is repulsive, soliton behvior is seen in the motion of holes in the condensate density, whose velocity it determined by the phase difference between adjoining pieces of condensate, in analogy to the familiar Josephson effect. We explore the properties of these solitons via elementary analytic models and computer simulation, and make specific suggestions for their experimental observation.Citation
