Modulational Instability in Bose?Einstein Condensates under Feshbach Resonance Management
Modulational Instability in Bose?Einstein Condensates under Feshbach Resonance Management
We investigate the modulational instability of nonlinear Schr{\"o}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 …
