Formation of solitons in atomic Bose-Einstein condensates by dark-state adiabatic passage
G. Juzeliunas, J. Ruseckas, P. Öhberg +1
We propose a new method of creating solitons in elongated Bose-Einstein Condensates (BECs) by sweeping three laser beams through the BEC. If one of the beams is in the first order…
Vortex sorter for Bose-Einstein condensates
G. Whyte, J. Veitch, P. Ohberg +1
We have designed interferometers that sort Bose-Einstein condensates into their vortex components. The Bose-Einstein condensates in the two arms of the interferometer are rotated w…
Dynamical transition from a quasi-one dimensional Bose-Einstein condensate to a Tonks-Girardeau gas
P. Ohberg, L. Santos
We analyze in detail the expansion of a 1D Bose gas after removing the axial confinement. We show that during its one-dimensional expansion the density of the Bose gas does not fol…
Slow light and the phase of a Bose-Einstein condensate
P. Ohberg
We investigate the propagation of light with ultra low group velocity in a Bose-Einstein condensate where the phase is not uniform. The light is shown to couple strongly to the pha…
Generation and interaction of solitons in Bose-Einstein condensates
S. Burger, L. D. Carr, P. Ohberg +2
Generation, interaction and detection of dark solitons in Bose-Einstein condensates is considered. In particular, we focus on the dynamics resulting from phase imprinting and densi…
Vortex-vortex interaction in two-component Bose-Einstein condensates
P. Ohberg, L. Santos
The vortex-vortex interaction in two-component Bose-Einstein condensates is shown to present characteristic effects not possible in single-component condensates. In particular, vor…
