Classical-like wakes past elliptical obstacles in atomic Bose-Einstein condensates
G. W. Stagg, A. J. Allen, C. F. Barenghi +1
We reinvestigate numerically the classic problem of two-dimensional superfluid flow past an obstacle. Taking the obstacle to be elongated (perpendicular to the flow), rather than t…
Generation and Decay of Two-Dimensional Quantum Turbulence in a Trapped Bose-Einstein Condensate
G. W. Stagg, A. J. Allen, N. G. Parker +1
In a recent experiment, Kwon et. al (arXiv:1403.4658 [cond-mat.quant-gas]) generated a disordered state of quantum vortices by translating an oblate Bose-Einstein condensate past a…
Vortex reconnections in atomic condensates at finite temperature
A. J. Allen, S. Zuccher, M. Caliari +3
The study of vortex reconnections is an essential ingredient of understanding superfluid turbulence, a phenomenon recently also reported in trapped atomic Bose-Einstein condensates…
Evaporative cooling of cold atoms at surfaces
J. Märkle, A. J. Allen, P. Federsel +5
We theoretically investigate the evaporative cooling of cold rubidium atoms that are brought close to a solid surface. The dynamics of the atom cloud are described by coupling a di…
Isotropic vortex tangles in trapped atomic Bose-Einstein condensates via laser stirring
A. J. Allen, N. G. Parker, N. P. Proukakis +1
The generation of isotropic vortex configurations in trapped atomic Bose-Einstein condensates offers a platform to elucidate quantum turbulence on mesoscopic scales. We demonstrate…
