Critical Behavior of a Trapped Interacting Bose Gas
Tobias Donner, Stephan Ritter, Thomas Bourdel +3
The phase transition of Bose-Einstein condensation is studied in the critical regime, when fluctuations extend far beyond the length scale of thermal de Broglie waves. Using matter…

Observing the Formation of Long-range Order during Bose-Einstein Condensation
Stephan Ritter, Anton Öttl, Tobias Donner +3
We have experimentally investigated the formation of off-diagonal long-range order in a gas of ultracold atoms. A magnetically trapped atomic cloud prepared in a highly nonequilibr…

Correlations and Counting Statistics of an Atom Laser
Anton Öttl, Stephan Ritter, Michael Köhl +1
We demonstrate time-resolved counting of single atoms extracted from a weakly interacting Bose-Einstein condensate of Rb atoms. The atoms are detected with a high-finesse op…
