The research projects in the BEC group



 

Rubidium team: BEC in a ring




Fig. 1

The combination of a dressed bubble-shaped trap with a vertical standing light wave gives rise to a ring trap, as we recently proposed. See the Rubidium project page and the SuperRing project.

Sodium team: BEC on a chip



A new experiment is under construction in the group. Visit its homepage!

Theory: Quantum anomaly in 2D




Fig. 3

In a recent theoric work, we studied the effect of a quantum anomaly on a Bose gas confined to 2 dimensions. The anomaly produces a small shift of the frequency of the breathing mode. We proposed a way to observe this effect in an experiment.
