Schemes for loading a Bose-Einstein condensate into a two-dimensional dipole trap
Yves Colombe, Demascoth Kadio, Maxim Olshanii +3
We propose two loading mechanisms of a degenerate Bose gas into a surface trap. This trap relies on the dipole potential produced by two evanescent optical waves far detuned from t…
Short-Distance Correlation Properties of the Lieb-Liniger System and Momentum Distributions of Trapped One-Dimensional Atomic Gases
Maxim Olshanii, Vanja Dunjko
We derive exact closed form expressions for the first few terms of the short-distance Taylor expansion of the one-body correlation function of the Lieb-Liniger gas. As an intermedi…
Berry's Phase Induced Bose-Einstein condensation into a Vortex State
M. Olshanii, M. Naraschewski
The existence of a geometric phase in magnetic traps can be used to Bose condense a magnetically trapped atomic gas into a vortex state. We propose an experimental setup where a ma…
Finite-Temperature Collective Excitation of a Bose-Einstein Condensate
Maxim Olshanii
We derive a simple formula for the finite-temperature shifts of the collective excitations of a Bose-Einstein condensate. To test the validity of our treatment we apply it to expla…
