3D-self-trapping of Rydberg-dressed BECs — •Nils Henkel1, Fabian Maucher1, Stefan Skupin1,2, and Thomas Pohl11Max Planck Institute for the Physics of Complex Systems, Nöthnitzer Straße 38, 01187 Dresden — 2Friedrich Schiller University, Institute of Condensed Matter Theory and Optics, 07743 Jena

We demonstrate that optical coupling of Bose-Einstein condensates can lead to the formation of stable three-dimensional bright solitons, bound by a single pair of Rydberg atoms. It is shown that off-resonant dressing with Rydberg d-states of Rubidium provides an anisotropic but attractive long range interaction which could enable the first realization of such three-dimensional structures. Taking into account both the long range interaction and the short range contact interaction between groundstates, we find large self-trapped three-dimensional solitons for realistic experimental parameters and study their stability.
