Is it possible to access the strongly interacting regime with a ⁶Li⁴⁰K Fermi-Fermi mixture? — •Andreas Trenkwalder¹, Christoph Kohstall^1,2, Frederik Spiegelhalder¹, Devang Naik¹, Gerhard Hendl¹, Florian Schreck¹, and Rudolf Grimm^1,2 — ¹Institut für Quantenoptik und Quanteninformation, Österreichische Akademie der Wissenschaften, Innsbruck, Austria — ²Institut für Experimentalphysik und Zentrum für Quantenphysik, Universität Innsbruck, Innsbruck, Austria

Interspecies Feshbach resonances in the ⁶Li⁴⁰K Fermi-Fermi mixture are closed-channel dominated and quite narrow. In order to determine if it is experimentally feasible to realize the strongly interacting regime, we measure the elastic and inelastic scattering properties across one of the widest interspecies resonances. Preliminary results are promising and indicate that the strongly interacting regime can indeed be reached.
