Three-body recombination rates near a Feshbach resonance within a two-channel contact interaction model
P. K. Sørensen, D. V. Fedorov, A. S. Jensen
We calculate the three-body recombination rate into a shallow dimer in a gas of cold bosonic atoms near a Feshbach resonance using a two-channel contact interaction model. The two-…
N-body Efimov states of trapped bosons
M. Thøgersen, D. V. Fedorov, A. S. Jensen
We demonstrate the possibility of existence of meta-stable N-body Efimov states in trapped Bose systems with large scattering length. We calculate spectra of trapped systems of N=3…
How to observe the Efimov effect
E. Nielsen, D. V. Fedorov, A. S. Jensen
We propose to observe the Efimov effect experimentally by applying an external electric field on atomic three-body systems. We first derive the lowest order effective two-body inte…
The structure of the atomic helium trimers: Halos and Efimov states
E. Nielsen, D. V. Fedorov, A. S. Jensen
The Faddeev equations for the atomic helium-trimer systems are solved numerically with high accuracy both for the most sophisticated realistic potentials available and for simple p…
