Quest for anisotropic solitons in dipolar Bose-Einstein condensates — •Patrick Köberle, Rüdiger Eichler, Jörg Main, and Günter Wunner — 1. Institut für Theoretische Physik, Uni Stuttgart

Quasi-two-dimensional bright solitons have been predicted to exist in dipolar Bose-Einstein condensates [1]. Yet, an experimental proof is still lacking. We first present calculations to mark the stability regions for experimentally relevant parameters. We then show the results of simulations of a planned experiment. They demonstrate how solitons can be created dynamically and reveal that this is still possible if some noise is added to the scattering length. This is of special importance because noise is always present in the experiment and could potentially destroy the soliton.
