Dynamical instability of a dark soliton in a quasi-one-dimensional Bose-Einstein condensate perturbed by an optical lattice
N. G. Parker, N. P. Proukakis, C. F. Barenghi +1
The motion of a dark soliton is investigated in a one-dimensional dilute Bose-Einstein condensate confined in a harmonic trap and an optical lattice. The harmonic trap induces a dy…
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…
Josephson spectroscopy of a dilute Bose-Einstein condensate in a double-well potential
E. Sakellari, M. Leadbeater, N. J. Kylstra +1
The dynamics of a Bose-Einstein condensate in a double-well potential are analysed in terms of transitions between energy eigenstates. By solving the time-dependent and time-indepe…
