Exact solutions and stability of rotating dipolar Bose-Einstein condensates in the Thomas-Fermi limit
We present a theoretical analysis of dilute gas Bose-Einstein condensates
with dipolar atomic interactions under rotation in elliptical traps. Working in
the Thomas-Fermi limit, we employ the classical hydrodynamic equations to first
derive the rotating condensate solutions and then consider their response to
perturbations. We thereby map out the regimes of stability and instability for
rotating dipolar Bose-Einstein condensates and in the latter case, discuss the
possibility of vortex lattice formation. We employ our results to propose
several novel routes to induce vortex lattice formation in a dipolar
condensate.Comment: 12 pages with 6 figure
The physics of dipolar bosonic quantum gases
This article reviews the recent theoretical and experimental advances in the
study of ultracold gases made of bosonic particles interacting via the
long-range, anisotropic dipole-dipole interaction, in addition to the
short-range and isotropic contact interaction usually at work in ultracold
gases. The specific properties emerging from the dipolar interaction are
emphasized, from the mean-field regime valid for dilute Bose-Einstein
condensates, to the strongly correlated regimes reached for dipolar bosons in
optical lattices.Comment: Review article, 71 pages, 35 figures, 350 references. Submitted to
