Mediated Interactions and Resonance in an Ultracold Bose-Fermi Mixture
ORAL
Abstract
Ultracold mixtures of bosonic and fermionic atoms are a powerful platform for quantum simulation. Our recent study of fermion-mediated interactions in a degenerate 6Li-133Cs mixture revealed puzzling beyond-mean-field behavior at strong boson-fermion attraction [Phys. Rev. Lett. 131, 083003 (2023)]. In this talk we summarize our current investigation of this regime using Kapitza-Dirac diffraction and in situ thermometry, which reveals a resonance-like structure in the mediated interaction far from the interspecies Feshbach resonance.
