Ground state properties of a trapped few-Boson system under rotation --beyond the "lowest Landau level" approximation--
arXiv:cond-mat/0105476 · doi:10.1103/PhysRevA.64.035601
Abstract
We consider a harmonically trapped few-Boson system under rotation and investigate the ground state properties beyond the usual ``lowest Landau level'' approximation by using exact diagonalizations in a restricted Hilbert subspace. We find that both the effective interaction energy and density distribution are strongly affected by the two-body interaction strength.
