Uniform Bose gases

For almost two decades harmonically-trapped ultracold atomic gases have been used with great success to study fundamental many-body physics in a flexible experimental setting. Recently, we achieved the first atomic Bose-Einstein condensate in an essentially uniform potential of an optical-box trap [1]. This opens unprecedented possibilities for closer connections with other many-body systems and the textbook models that rely on the translational symmetry of the system. I will present our first experiments on this new system, including the first observation of the quantum Joule-Thomson effect [2], which was theoretically predicted more than 70 years ago.
