Resonant atom-dimer collisions in cesium: Testing universality at positive scattering lengths
Alessandro Zenesini, Bo Huang, Martin Berninger +3
We study the collisional properties of an ultracold mixture of cesium atoms and dimers close to a Feshbach resonance near 550G in the regime of positive -wave scattering lengths…
Feshbach resonances, weakly bound molecular states and coupled-channel potentials for cesium at high magnetic fields
Martin Berninger, Alessandro Zenesini, Bo Huang +6
We explore the scattering properties of ultracold ground-state Cs atoms at magnetic fields between 450 G (45 mT) and 1000 G. We identify 17 new Feshbach resonances, including two v…
Resonant Five-body Recombination in an Ultracold Gas of Bosonic Atoms
A. Zenesini, B. Huang, M. Berninger +6
We combine theory and experiment to investigate five-body recombination in an ultracold gas of atomic cesium at negative scattering length. A refined theoretical model, in combinat…
Efimov Resonances in Ultracold Quantum Gases
F. Ferlaino, A. Zenesini, M. Berninger +3
Ultracold atomic gases have developed into prime systems for experimental studies of Efimov three-body physics and related few-body phenomena, which occur in the universal regime o…
Universality of the Three-Body Parameter for Efimov States in Ultracold Cesium
M. Berninger, A. Zenesini, B. Huang +6
We report on the observation of triatomic Efimov resonances in an ultracold gas of cesium atoms. Exploiting the wide tunability of interactions resulting from three broad Feshbach…
Magnetically Controlled Exchange Process in an Ultracold Atom-Dimer Mixture
S. Knoop, F. Ferlaino, M. Berninger +5
We report on the observation of an elementary exchange process in an optically trapped ultracold sample of atoms and Feshbach molecules. We can magnetically control the energetic n…
