Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances
J. Ulmanis, S. Häfner, R. Pires +3
We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 G and 1000 G. Cl…

Analyzing Feshbach resonances -- A Li -Cs case study
Rico Pires, Marc Repp, Juris Ulmanis +7
We provide a comprehensive comparison of a coupled channels calculation, the asymptotic bound state model (ABM), and the multichannel quantum defect theory (MQDT). Quantitative res…

Observation of Efimov Resonances in a Mixture with Extreme Mass Imbalance
R. Pires, J. Ulmanis, S. Häfner +4
We observe two consecutive heteronuclear Efimov resonances in an ultracold Li-Cs mixture by measuring three-body loss coefficients as a function of magnetic field near a Feshbach r…
