High-spin molecular quantum gases

We study ultracold gases of magnetic atoms, such as dysprosium, to create new ultracold molecular species. Molecules in the ground state will inherit the large orbital angular momentum of dysprosium and display Ω-doubling. The many, closely spaced levels in Ω-doublets can be easily polarized with external fields and offer new opportunities for controlling molecular interactions and suppressing ultracold chemical reactions.
We will explore new shielding methods to create a long-lived gas of strongly interacting bosonic molecules and further cool it down to realize a Bose-Einstein Condensate of polar molecules. With this, we will investigate new phases of quantum matter, such as supersolids, quantum crystal, and topological superfluids.

Single-molecule-resolved ultracold collisions and quantum chemistry

Levaraging on the recent advances in the field of optical tweezers, we will realize a configurable array where atoms and molecules are manipulated at the single-particle level. High-fidelity control over the internal and external degrees of freedom of atoms and molecules will allow us to study exotic ultracold interactions, such as molecule-Rydberg and ion-atom collisions.
