En route to many-body physics with 23Na-40K ground-state polar molecules — •Zhenkai Lu, Nikolaus Buchheim, Tobias Schneider, Immanuel Bloch, and Christoph Gohle — Max-Planck-Institut für Quantenoptik, Hans-Kopfermann-Straße 1, 85748 Garching, Germany

Ultra cold quantum gases with long-range dipolar interaction promise exciting new possibilities for quantum simulation of strongly interacting many-body systems.

New classes of many-body phases (like super solids and stripe phases) are on the horizon and ferroelectric phases of highly polarizable systems are expected [1][2].

We have constructed an experimental apparatus aiming to create ultracold chemical stable ground-state 23Na-40K molecules. We will present the design considerations, implementation and performance of the experiment. In addition, we will present our recent results on producing 23Na-40K Feshbach molecules.
