Two-dimensional solitons in dipolar Bose-Einstein condensates — •Patrick Köberle, Jörg Main, and Günter Wunner — 1. Institut für Theoretische Physik, Universität Stuttgart, 70550 Stuttgart
One of the key features of dipolar Bose-Einstein condensates is their instability with respect to collapse. It has been shown in [1] how this instability is affected by the shape of an external (3D) trap. However, according to [2], it is possible to create stable condensates which are only trapped in one direction perpendicular to the polarization axis. Using a numerical simulation we demonstrate how these two-dimensional solitons can be created in experiment, in particular in 52Cr condensates.
