Universal three-body recombination and Efimov resonances in an ultracold Li-Cs mixture

J. Ulmanis, S. Häfner, R. Pires +4

We study Efimov resonances via three-body loss in an ultracold two-component gas of fermionic ${}^6$Li and bosonic ${}^{133}$Cs atoms close to a Feshbach resonance at 843~G, extending…
