The BEC group is expert in manipulating Bose-EInstein condensate in radiofrequency dressed potentials. Our current experimental studies in this field focus on exploring the superfluid dynamics of degenerate Bose gases on a curved surface or in an elongated trap. We are also interested in the physics of ultracold gases in lower dimensions (1D, 2D).
We have currently two experimental projects: rubidium atoms on a curved surface and sodium on an atom chip.
The BEC group is a member of QuanTiP.
