Josephson tunnelling of a phase-imprinted Bose-Einstein condensate in a time-dependent double-well potential
E. Sakellari, N. P. Proukakis, M. Leadbeater +1
This paper discusses the feasibility of experimental control of the flow direction of atomic Bose-Einstein condensates in a double-well potential using phase-imprinting. The flow i…
Josephson Current Counterflow in Atomic Bose-Einstein Condensates
E. Sakellari, N. P. Proukakis, M. Leadbeater +1
Josephson weak links in superconductors can be engineered such that the phase difference across the junction is (-junction),leading to the reversal of the current. The condi…
Deformation of dark solitons in inhomogeneous Bose-Einstein condensates
N. G. Parker, N. P. Proukakis, M. Leadbeater +1
A dark soliton becomes unstable when it is incident on a background density gradient, and the induced instability results in the emission of sound. Detailed quantitative studies of…
Soliton-sound interactions in quasi-one-dimensional Bose-Einstein condensates
N. G. Parker, N. P. Proukakis, M. Leadbeater +1
Longitudinal confinement of dark solitons in quasi-one-dimensional Bose-Einstein condensates leads to sound emission and reabsorption. We perform quantitative studies of the dynami…
Creation of solitons and vortices by Bragg reflection of Bose-Einstein condensates in an optical lattice
R. G. Scott, A. M. Martin, T. M. Fromhold +3
We study the dynamics of Bose-Einstein condensates in an optical lattice and harmonic trap. The condensates are set in motion by displacing the trap and initially follow simple sem…
Decay of superfluid turbulence via Kelvin wave radiation and vortex reconnections
M. Leadbeater, D. C. Samuels, C. F. Barenghi +1
The elementary processes involved in the decay of superfluid turbulence in the limit of low temperature are studied by numerical simulations of vortex ring collisions. We find that…
