We report on the development of a new experiment for producing mixtures of dysprosium atoms and molecules strongly coupled to an optical cavity, with the ultimate goal of using the cavity fields to control ultracold chemistry. Along this path, we developed a simple laser cooling scheme that allowed us to simultaneously trap two isotopes of dysprosium and realize a new stable and strongly dipolar Bose-Bose mixture in the quantum degenerate regime [1]. In a separate atomic beam experiment, we showed that dysprosium atoms can acquire a large electric dipole moment when prepared in a doublet of opposite-parity excited states, enabling the realization of a unique doubly polar quantum gas [2]. These results may enable the realization of new forms of supersolids.References:[1] M. Dürbeck et al. Phys. Rev. A 114, L031301 (2026)[2] J. Seifert et al. arXiv:2511.14225 (2025)
