Two-body correlations in Bose condensates
O. Sorensen, D. V. Fedorov, A. S. Jensen +1
We formulate a method to study two-body correlations in a condensate of N identical bosons. We use the adiabatic hyperspheric approach and assume a Faddeev like decomposition of th…
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…
Three-Body Halos in Two Dimensions
E. Nielsen, D. V. Fedorov, A. S. Jensen
A method to study weakly bound three-body quantum systems in two dimensions is formulated in coordinate space for short-range potentials. Occurrences of spatially extended structur…
