Manipulation of a dipolar Bose-Einstein condensate using an electro-optical deflector system — •Matthias Schmitt, Holger Kadau, Matthias Wenzel, Igor Ferrier-Barbut, and Tilman Pfau — 5. Physikalisches Institut and Center for Integrated Quantum Science and Technology, Universität Stuttgart, Pfaffenwaldring 57, 70569 Stuttgart, Germany

Strongly dipolar quantum gases enable the observation of many-body phenomena with anisotropic, long-range interactions. Observing these effects can be enhanced by an initial preparation of the atomic density distribution in multi-well [1] or ring-shaped potentials [2] as well as in-situ imaging.
We present the first results on tailored potentials imprinted on a Bose-Einstein condensate of dysprosium atoms. The potentials are created with a 532 nm laser modulated with an electro-optical deflector system and a Pockels cell. The light is focused on the atomic cloud using a diffraction-limited custom objective with high numerical aperture.
