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…

Dark solitons in a two-component Bose-Einstein condensate
P. Ohberg, L. Santos
The creation and interaction of dark solitons in a two-component Bose-Einstein condensate is investigated. For a miscible case, the interaction of dark solitons in different compon…

Four-wave mixing in degenerate atomic gases
P. Villain, P. Ohberg, L. Santos +2
We study the process of four-wave mixing (4WM) in ultracold degenerate atomic gases. In particular we address the problem of 4WM in boson-fermion mixtures. We develop an approximat…
