Abstract

We derive an analytic formula which describes the final bound state dependence in ultracold three-body recombination. Using an energy-dependent loss parameter, the recently observed broad resonance in an ultracold gas of {sup 6}Li atoms [T. B. Ottenstein, T. Lompe, M. Kohnen, A. N. Wenz, and S. Jochim, Phys. Rev. Lett. 101, 203202 (2008); J. H. Huckans, J. R. Williams, E. L. Hazlett, R. W. Stites, and K. M. O'Hara, Phys. Rev. Lett. 102, 165302 (2009)] is described quantitatively. We also provide an analytic and approximation for the three-body recombination rate which encapsulates the underlying physics of the universal three-body recombination process.

Evidence for an Excited-State Efimov Trimer in a Three-Component Fermi Gas

Journal Article Williams, J; Hazlett, E; Huckans, J; ... - Physical Review Letters

We observe enhanced three-body recombination in a three-component {sup 6}Li Fermi gas attributable to an excited Efimov trimer state intersecting the three-atom scattering threshold near 895 G. From measurements of the recombination rate we determine the Efimov parameters kappa{sub *} and eta{sub *} for the universal region above 600 G which includes three overlapping Feshbach resonances. The value of kappa{sub *} also predicts the locations of loss features previously observed near 130 and 500 G [T. B. Ottenstein et al., Phys. Rev. Lett. 101, 203202 (2008); J. H. Huckans et al., Phys. Rev. Lett. 102, 165302 (2009)] suggesting they aremore »« less

Universal trimer in a three-component Fermi gas

Journal Article Wenz, A; Lompe, T; Ottenstein, T; ... - Physical Review. A

We show that the recently measured magnetic field dependence of three-body loss in a three-component mixture of ultracold {sup 6}Li atoms [T. B. Ottenstein et al., Phys. Rev. Lett. 101, 203202 (2008); J. H. Huckans et al., Phys. Rev. Lett. 102, 165302 (2009)] can be explained by the presence of a universal trimer state. Previous work suggested a universal trimer state as a probable explanation, yet it failed to get good agreement between theory and experiment over the whole range of magnetic fields. For our description we adapt the theory of Braaten and Hammer [Phys. Rep. 428, 259 (2006)] formore »« less

Moderation of recombination in an ultracold laser-produced plasma

Journal Article Tkachev, Aleksei; Yakovlenko, Sergei - Quantum Electronics (Woodbury, N.Y.)

It is shown that the recent production [T C Killian et al. Phys. Rev. Lett. 83 4776 (1999)] of an ultracold laser plasma (N{sub e} {approx} 2 x 10{sup 9} cm{sup -3}, T{sub e} {approx} 0.1 K, T{sub i} {approx} 10 {mu}K) can be considered as the first experimental demonstration of the metastable state of a supercooled plasma which we predicted theoretically. Our theory provides an explanation for the moderation of three-body recombination observed in the above-cited paper. We present the calculations that simulate the conditions of the ultracold-plasma experiments. (interaction of laser radiation with matter. laser plasma)

Relaxation of Rydberg states in an ultracold plasma

Journal Article Tkachev, Aleksei; Yakovlenko, Sergei - Quantum Electronics (Woodbury, N.Y.)

The variations in the population densities of Rydberg states (with principal quantum number n {approx} 50 - 100) in an expanding ultracold laser plasma (N{sub e} {approx} 10{sup 9} - 10{sup 4} cm{sup -3}, T{sub e} {approx} 10 - 0.5 K) are calculated. The electron temperature measurement from the population densities of Rydberg states (T C Killian et al., Phys. Rev. Lett., vol. 86, p. 3759, 2001) is shown to be described by the conventional three-body recombination theory with the inclusion of recombination heating of free electrons.

Nuclear-Spin-Independent Short-Range Three-Body Physics in Ultracold Atoms

Journal Article Gross, Noam; Shotan, Zav; Khaykovich, Lev; ... - Physical Review Letters

We investigate three-body recombination loss across a Feshbach resonance in a gas of ultracold {sup 7}Li atoms prepared in the absolute ground state and perform a comparison with previously reported results of a different nuclear-spin state [N. Gross et al., Phys. Rev. Lett. 103, 163202 (2009)]. We extend the previously reported universality in three-body recombination loss across a Feshbach resonance to the absolute ground state. We show that the positions and widths of recombination minima and Efimov resonances are identical for both states which indicates that the short-range physics is nuclear-spin independent.
