High-spin molecular quantum gases

We use a mixture of dysprosium and chromium atoms to create a quantum gas of polar molecules with large magnetic and electric dipole moment. These molecules will inherit the large orbital angular momentum of atomic dysprosium. This will result in several closely spaced Ω-doublets that can be oriented in small electric fields.
These states will offer new possibilities for controlling interactions in molecular system and suppress inelastic and reactive losses via robust shielding mechanisms. We will 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.
