Ultracold gases articles from across Nature Portfolio

Ultracold gases are ensembles of atoms held at a temperature near absolute zero. Such systems enable the creation of exotic phenomena such as Bose–Einstein condensation. Ultracold gases are also useful simulating condensed-matter systems because their tunability opens the door to effects that are otherwise difficult to observe.

    Controlling the response of a material to light at the single-atom level is a key factor for many quantum technologies. An experiment now shows how to control the optical properties of an atomic array by manipulating the state of a single atom.

    The observation of quantized vortices in a rotating gas of magnetic atoms confirms a long-standing prediction and has far-reaching implications for the study of phenomena related to superfluidity.

    An ultracold spinor Bose gas was used to achieve advanced experimental control and detection of an easy-plane ferromagnet, allowing observation of the system as it approaches equilibrium. The measurements revealed twofold superfluidity in the spin and density degrees of freedom with very different critical speeds.

    A quantum rotor periodically kicked stops absorbing energy after a certain time and enters into a localized regime. Two experiments with cold atoms have now shown how many-body interactions can suppress dynamical localization.
