Disordered quantum gases with tunable interaction

Group leader : Thomas BOURDEL

We study quantum Bose gases in particular in small dimensions, where quantum and thermal fluctuations play an important role. We work with potassium 39, an atom that has resonances of Feshbach allowing the control of the interactions between atoms. We can also add disorder with a speckle potential. The disorder competes for transport properties with interactions that induce superfluidity.
