Strongly dipolar quantum gases enable the observation of many-body phenomena with anisotropic, long-range interaction. Rotonic features, 2D stable solitons and the supersolid state are some of the exotic many-body phenomena predicted for dipolar quantum gases.
Recently quantum degeneracy of dysprosium, the element with the strongest magnetic dipole moment, was achieved. After preparation of a dysprosium condensate we plan to use a diffraction-limited custom objective with high numerical aperture for in-situ imaging. This allows to reveal the structure of the quantum gas on a sub-micron level. Combined with an electro-optical deflector system and a Pockels cell the objective is used to create tailored potentials. With this setup we want to investigate multi-well potentials [1] or ring-shaped potentials [2].
