Journal ArticleDOI
Evidence for efimov quantum states in an ultracold gas of caesium atoms
T. Kraemer,Manfred J. Mark,P. Waldburger,Johann G. Danzl,Cheng Chin,Cheng Chin,B. Engeser,A. D. Lange,K. Pilch,Antti Jaakkola,Hanns-Christoph Nägerl,Rudolf Grimm,Rudolf Grimm +12 more
TL;DR: In this article, the Efimov trimer state was shown to exist in an ultracold gas of caesium atoms and its signature was observed as a giant three-body recombination loss when the strength of the two-body interaction is varied.
Journal ArticleDOI
Observation of interspecies Feshbach resonances in an ultracold Rb-Cs mixture
K. Pilch,A. D. Lange,A. Prantner,G. Kerner,Francesca Ferlaino,Hanns-Christoph Nägerl,Rudolf Grimm +6 more
TL;DR: In this article, the interspecies Feshbach resonances in an ultracold, optically trapped mixture of Rb and Cs atoms were observed in a magnetic field range up to 300 G.
Journal ArticleDOI
Determination of atomic scattering lengths from measurements of molecular binding energies near Feshbach resonances
A. D. Lange,K. Pilch,A. Prantner,Francesca Ferlaino,B. Engeser,Hanns-Christoph Nägerl,Rudolf Grimm,Cheng Chin +7 more
TL;DR: In this article, an analytic model was proposed to calculate the atomic scattering length near a Feshbach resonance from data on the molecular binding energy using magnetic-field modulation spectroscopy in a range where one broad and two narrow resonances overlap.

Experimental Evidence for Efimov Quantum States
Hanns-Christoph Naegerl,T. Kraemer,Michael Mark,P. Waldburger,Johann G. Danzl,B. Engeser,A. D. Lange,K. Pilch,Antti Jaakkola,Cheng Chin,Rudolf Grimm +10 more
TL;DR: In this article, the Efimov trimer was observed in an ultracold thermal gas of cesium atoms and its signature was shown to be a giant three-body recombination loss when the strength of the two-body interaction is varied near a Feshbach resonance.

TL;DR: In this paper, the Efimov resonance was observed in an ultracold thermal gas of cesium atoms, and the resonance occurred in the range of large negative two-body scattering lengths.
