Stability of quasi-two-dimensional Bose-Einstein condensates with dominant dipole-dipole interactions
arXiv:cond-mat/0506368 · doi:10.1103/PhysRevA.73.031602
Abstract
We consider quasi-two-dimensional atomic/molecular Bose-Einstein condensates with both contact and dipole-dipole interactions. It is shown that, as a consequence of the dimensional reduction, and within mean-field theory, the condensates do not develop unstable excitation spectra, even when the dipole-dipole interaction completely dominates the contact interaction.
