Quantum gases with tunable interaction

Activité scientifique

We especially study gases in reduce dimensions (1D, 2D), where quantum and thermal fluctuations are most important. Importantly, we work with potassium 39, a bosonic element having nice magnetically tunable Feshbach resonances, thus permitting the control of the interatomic interaction. Recently, we are working with coherently coupled Bose-Einstein condensates in different spin-states. It enables the control of the interaction in a new way and permits to induce three-body interactions in quantum gases.
