Universality of the three-body parameter for Efimov states in ultracold cesium.

Berninger, M. and Zenesini, A. and Huang, B. and Harm, W. and Nägerl, H.C. and Ferlaino, F. and Grimm, R. and Julienne, P.S. and Hutson, J.M. (2011) 'Universality of the three-body parameter for Efimov states in ultracold cesium.', Physical review letters., 107 (12). p. 120401.

Abstract

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 resonances in the same spin channel, we measure magnetic-field dependent three-body recombination loss. The positions of the loss resonances yield corresponding values for the three-body parameter, which in universal few-body physics is required to describe three-body phenomena and, in particular, to fix the spectrum of Efimov states. Our observations show a robust universal behavior with a three-body parameter that stays essentially constant.
