Breakdown of the mean field for dark solitons of dipolar bosons in a one-dimensional harmonic trap
We directly compare the mean-field and the many-body approaches, in a one-dimensional Bose system in a harmonic trap. Both contact and dipolar interactions are considered. We obtain eigenstates of the many-body system by exact diagonalization with a truncated basis. We propose a multiatom version of...
