The BEC Group at Paris Nord

A group belonging to Laboratoire de physique des lasers



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 on a curved surface. 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.

Join us!

The BEC group is a member of QuanTiP.
