Propagation and Stability of Bright Solitons in Bose-Einstein Condensates
Abstract
Many schemes for producing viable atom optics rely upon the generation and transport of bright solitons using Bose-Einstein condensates. Since the solitons form from condensates with negative scattering lengths, their stability, given a tendency to collapse and regenerate, becomes an important concern. We have studied bright soliton generation and propagation using a multicomponent time-dependent nonlinear Schrödinger equation, solved by large-scale computational simulations in two and three dimensions with both Real Space Product(L. Collins et. al.), Comp. Phys. Comm. 114, 15 (1998) and Discrete variable representation(B.I. Schneider and D. L. Feder, Phys. Rev. A 59), 2232 (1999) methods. We investigate a variety of production and transport mechanisms.
