The Bose-Einstein Condensation of dilute atomic gases is the subject of intense studies since its first demonstration in 1995. Our group is expert in manipulating atoms in radiofrequency dressed potentials. Our current experimental studies in this field focus on testing the superfluidity of degenerate Bose gases in a toroidal trap. We are also interested in the physics of ultracold gases in lower dimensions (1D, 2D).

We have currently two experimental projects: rubidium atoms in a ring potential and sodium on an atom chip.

Join us!

The BEC group is a member of IFRAF and SIRTEQ.
