Three-body Thomas-Ehrman shifts of analog states of Ne and N
E. Garrido, D. V. Fedorov, A. S. Jensen
The lowest-lying states of the Borromean nucleus Ne (O+ + ) and its mirror nucleus N (N+ + ) are compared by using the hyperspheric adiabati…
Condensates and correlated boson systems
O. Sørensen, D. V. Fedorov, A. S. Jensen
We study two-body correlations in a many-boson system with a hyperspherical approach, where we can use arbitrary scattering length and include two-body bound states. As a special a…
Stability, effective dimensions, and interactions for bosons in deformed fields
O. Sørensen, D. V. Fedorov, A. S. Jensen
The hyperspherical adiabatic method is used to derive stability criteria for Bose-Einstein condensates in deformed external fields. An analytical approximation is obtained. For con…
Complex scaling of the hyper-spheric coordinates and Faddeev equations
D. V. Fedorov, E. Garrido, A. S. Jensen
We implement complex scaling of Faddeev equations using hyper-spheric coordinates and adiabatic expansion. Complex scaling of coordinates allows convenient calculations of three-bo…
Structure of boson systems beyond the mean-field
O. Sørensen, D. V. Fedorov, A. S. Jensen
We investigate systems of identical bosons with the focus on two-body correlations. We use the hyperspherical adiabatic method and a decomposition of the wave function in two-body…
Correlated N-boson systems for arbitrary scattering length
O. Sørensen, D. V. Fedorov, A. S. Jensen
We investigate systems of identical bosons with the focus on two-body correlations and attractive finite-range potentials. We use a hyperspherical adiabatic method and apply a Fadd…
