The three-body parameter for Efimov states in lithium-6
Bo Huang, Kenneth M. O'Hara, Rudolf Grimm +2
We present a state-of-the-art reanalysis of experimental results on Efimov resonances in the three-fermion system of Li. We discuss different definitions of the 3-body paramete…
The nonlinear Dirac equation: Preparation and stability of relativistic vortices in Bose-Einstein condensates
L. H. Haddad, K. M. O'Hara, Lincoln D. Carr
We propose a detailed experimental procedure for preparing relativistic vortices, governed by the nonlinear Dirac equation, in a two-dimensional Bose-Einstein condensate (BEC) in a…
Realization of a Resonant Fermi Gas with a Large Effective Range
E. L. Hazlett, Y. Zhang, R. W. Stites +1
We have measured the interaction energy and three-body recombination rate for a two-component Fermi gas near a narrow Feshbach resonance and found both to be strongly energy depend…
