Development of a Cryogenic Beam Source for Cold Calcium Monofluoride Molecules — •Phillip Groß, Ole Prochnow, Alexandra Köpf, and Tim Langen — 5. Physikalisches Institut, Universität Stuttgart

The production of ultracold molecular quantum gases promises to add long-range dipolar interactions to the quantum simulation toolbox. Here we first show theoretically that such dipolar interactions can lead to the formation of new phases of matter in bulk molecular Bose-Einstein condensates, such as droplet states and supersolids. Second, we present a new setup to realize these phases of matter in an experiment. In this setup we work with calcium monofluoride molecules, which are characterized by large electric dipole moments and well-established laser cooling strategies. In a first step to create a gas of these molecules with high phase space density, we present the design of a cryogenic buffer gas beam source, as well as extensive simulations of transversal and longitudinal laser cooling of the resulting molecular beam.
