We analyse the static solutions of attractive Bose-Einstein condensates under transverse confinement, both with and without axial confinement. By full numerical solution of the Gross-Pitaevskiiâ€¦ (More)

Motivated by recent experimental observations, we study theoretically multiple bright solitary waves of trapped BoseEinstein condensates. Through variational and numerical analyses, we determine theâ€¦ (More)

A dark soliton oscillating in an elongated harmonically confined atomic Bose-Einstein condensate continuously exchanges energy with the sound field. Periodic optical paddles are employed toâ€¦ (More)

Dark solitons have been observed in homogeneous optical fibers, and, more recently, in harmonically confined atomic Bose-Einstein condensates. This paper presents an overview of some of the commonâ€¦ (More)

Classically it is impossible to have transport without transit, i.e., if the points 1, 2, and 3 lie sequentially along a path then an object moving from 1 to 3 must, at some point in time, be locatedâ€¦ (More)

We show that "weak" elliptical deformation of an atomic Bose-Einstein condensate rotating at close to the quadrupole instability frequency leads to turbulence with a Kolmogorov energy spectrum. Theâ€¦ (More)

The low temperature dynamics of a vortex in a trapped quasi-two-dimensional Bose-Einstein condensate are studied quantitatively. Precession of an off-centered vortex in a dimple trap, embedded in aâ€¦ (More)

We investigate numerically the response of an atomic Bose-Einstein condensate to a weakly-elliptical rotating trap over a large range of rotation frequencies. We analyse the quadrupolar shapeâ€¦ (More)

Anaerobic digestion enables the water industry to treat wastewater as a resource for generating energy and recovering valuable by-products. The complexity of the anaerobic digestion process hasâ€¦ (More)

We perform a theoretical study into how dipole-dipole interactions modify the properties of superfluid vortices within the context of a two-dimensional atomic Bose gas of co-oriented dipoles. Theâ€¦ (More)
