Self-bound Dipolar Droplets and Supersolids in Molecular Bose-Einstein Condensates — •Tim Langen — 5. Physikalisches Institut and Center for Integrated Quantum Science and Technology, Universität Stuttgart, Germany

I will discuss the prospects of exploring quantum many-body physics with ultracold molecular gases.

On the theory side, I will present a numerical study of molecular Bose-Einstein condensates with strong dipole-dipole interactions. We observe the formation of self-bound droplets, and explore phase diagrams that feature a variety of exotic supersolid states. In all of these cases, the large and tunable molecular dipole moments enable the study of unexplored regimes and phenomena, including liquid-like density saturation and universal stability scaling laws for droplets, as well as pattern formation and the limits of droplet supersolidity.

On the experimental side, I will discuss progress in molecular laser cooling towards the ultracold regime. I will further present a realistic approach to realize both the collisional stability of ultracold molecular gases and the independent tunability of their contact and dipolar interaction strengths using a combination of microwave and DC electric fields.

Taken together, these results provide both a blueprint and a benchmark for near-future experiments with bulk molecular Bose-Einstein condensates.
