Abstract

Experimental and theoretical investigations were performed on dark solitons in Bose-Einstein condensates of 87Rb, produced by phase imprinting. A highly anisotropic confining potential allowed a close look at the 1D situation where dark solitons are expected to be dynamically stable. The evolution of the density minima traveling at a smaller velocity than the speed of sound was observed by monitoring the evolution of the density profile. By comparing the analytical and numerical solutions of the 3D Gross-Pitaevskii equation for the experimental conditions, the density minima were identified as moving dark solitons.
