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…
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…
