From strongly-interacting Bose-Fermi mixtures to ultracold molecules
… molecules of ²³Na⁴⁰K. The rich phase diagram of Bose-Fermi mixtures was studied with our system of bosonic ²³Na and fermionic ⁴⁰K atoms. When the fermions were immersed as a minority species within a Bose-Einstein condensate, the system realized the canonical Bose polaron quasiparticle, which is …

Dimers, Trimers and their Superpositions in a Bose-Fermi Mixture
… on few- and many-body bound states in a Bose-Fermi mixture of ultracold 23Na and 40K atoms. We examine the formation of dimers and trimers in a balanced, thermal mixture and their evolution into strongly interacting Bose polarons with hybridized dimer and trimer character when we instead …

Few- and Many-body Physics with Strongly Interacting Bose Gases
… and many-body physics in strongly interacting Bose gases. Our experimental platform uses Bose-Einstein condensates and cold thermal gases of 39K in different hyperfine states or their combinations, trapped in a quasi-uniform optical potential. We focus on the regime of strong interatomic …

Strongly interacting quantum mixtures of ultracold atoms
… presented. Firstly, the direct cooling of "K to Bose-Einstein condensation is presented. Then the 41K atoms provide the coolant for 6Li and 40K, achieving a triply degenerate gas of 6Li -40K -41K. In particular, a broad interspecies Feshbach resonance between 40K -41K is observed, opening a new …
