Nonadiabatic dynamics of dark solitons

Abstract

We show that under certain conditions the dark soliton solutions of the defocusing nonlinear Schrr odinger equation can be less stable than their bright counterparts. This is due to the tendency of a dark soliton under external perturbation to generate dispersive waves that organize themselves in a \shelf" around the pulse wings, as exempliied by the simple… (More)
