Observation of two-dimensional Anderson localisation of ultracold atoms
Donald H. White, Thomas A. Haase, Dylan J. Brown +6
Anderson localisation -- the inhibition of wave propagation in disordered media -- is a surprising interference phenomenon which is particularly intriguing in two-dimensional (2D)…
Splitting and recombination of bright-solitary-matter waves
Oliver J. Wales, Ana Rakonjac, Thomas P. Billam +3
Solitons are long-lived wavepackets that propagate without dispersion and exist in a wide range of one-dimensional (1D) nonlinear systems. A Bose-Einstein condensate trapped in a q…
Non-integrable dynamics of matter-wave solitons in a density-dependent gauge theory
R. J. Dingwall, M. J. Edmonds, J. L. Helm +2
We study interactions between bright matter-wave solitons which acquire chiral transport dynamics due to an optically-induced density-dependent gauge potential. Through numerical s…
Measuring the disorder of vortex lattices in a Bose-Einstein condensate
A. Rakonjac, A. L. Marchant, T. P. Billam +4
We report observations of the formation and subsequent decay of a vortex lattice in a Bose-Einstein condensate confined in a hybrid optical-magnetic trap. Vortices are induced by r…
Quantum reflection of bright solitary matter-waves from a narrow attractive potential
A. L. Marchant, T. P. Billam, M. M. H. Yu +6
We report the observation of quantum reflection from a narrow, attractive, potential using bright solitary matter-waves formed from a 85Rb Bose-Einstein condensate. We create narro…
Sagnac Interferometry Using Bright Matter-Wave Solitons
J. L. Helm, S. L. Cornish, S. A. Gardiner
We use an effective one-dimensional Gross-Pitaevskii equation to study bright matter-wave solitons held in a tightly confining toroidal trapping potential, in a rotating frame of r…
Splitting bright matter-wave solitons on narrow potential barriers: quantum to classical transition and applications to interferometry
J. L. Helm, S. J. Rooney, Christoph Weiss +1
We study bright solitons in the Gross-Pitaevskii equation as they are split and recombined in a low energy system. We present new analytic results determining the general region in…
Bright matter-wave soliton collisions at narrow barriers
John L. Helm, Thomas P. Billam, Simon A. Gardiner
We study fast-moving bright solitons in the focusing nonlinear Schrödinger equation perturbed by a narrow Gaussian potential barrier. In particular, we present a general and compre…
