Modulational Instability in Bose-Einstein Condensates under Feshbach Resonance Management
arXiv:cond-mat/0404664 · doi:10.1238/Physica.Topical.107a00027
Abstract
We investigate the modulational instability of nonlinear Schr{ö}dinger equations with periodic variation of their coefficients. In particular, we focus on the case of the recently proposed, experimentally realizable protocol of Feshbach Resonance Management for Bose-Einstein condensates. We derive the corresponding linear stability equation analytically and we show that it can be reduced to a Kronig-Penney model, which allows the determination of the windows of instability. The results are tested numerically in the absence, as well as in the presence of the magnetic trapping potential.
