A superfluid boundary layer
G. W. Stagg, N. G. Parker, C. F. Barenghi
We model the superfluid flow of liquid helium over the rough surface of a wire (used to experimentally generate turbulence) profiled by atomic force microscopy. Numerical simulatio…
Structure formation during the collapse of a dipolar atomic Bose-Einstein condensate
N. G. Parker, C. Ticknor, A. M. Martin +1
We investigate the collapse of a trapped dipolar Bose-Einstein condensate. This is performed by numerical simulations of the Gross-Pitaevskii equation and the novel application of…
Collapse times of dipolar Bose-Einstein condensates
C. Ticknor, N. G. Parker, A. Melatos +3
We investigate the time taken for global collapse by a dipolar Bose-Einstein condensate. Two semi-analytical approaches and exact numerical integration of the mean-field dynamics a…
Bright solitary waves of atomic Bose-Einstein condensates under rotation
N. A. Jamaludin, N. G. Parker, A. M. Martin
We analyse the rotation of bright solitary waves formed of atomic Bose-Einstein condensates with attractive atomic interactions. By employing a variational technique and assuming a…
Matterwave Transport Without Transit
M. Rab, J. H. Cole, N. G. Parker +3
Classically it is impossible to have transport without transit, i.e., if the points one, two and three lie sequentially along a path then an object moving from one to three must, a…
Rotation of an atomic Bose-Einstein condensate with and without a quantized vortex
I. Corro, N. G. Parker, A. M. Martin
We theoretically examine the rotation of an atomic Bose-Einstein condensate in an elliptical trap, both in the absence and presence of a quantized vortex. Two methods of introducin…
