Application of the Feshbach-resonance management to a tightly confined Bose-Einstein condensate
arXiv:0904.0480 · doi:10.1103/PhysRevA.79.045602
Abstract
We study suppression of the collapse and stabilization of matter-wave solitons by means of time-periodic modulation of the effective nonlinearity, using the nonpolynomial Schroedinger equation (NPSE) for BEC trapped in a tight cigar-shaped potential. By means of systematic simulations, a stability region is identified in the plane of the modulation amplitude and frequency. In the low-frequency regime, solitons feature chaotic evolution, although they remain robust objects.
