Date Time Current trend reversed The demonstration that a tiny cloud of atoms can be turned from a heat engine into a cooler by cranking up the interactions between the particles provides both deep fundamental insight and a possible template for more efficient thermoelectric devices. Artistic impression of the experiment in which Häusler and colleagues first heat one of two quantum-gas clouds and then connect them with a two-dimensional channel, such that they can equilibrate. (Graphics: D. Husmann & S. Häusler, ETH Zurich) When a piece of conducting material is heated up at one of its ends, a voltage difference can build up across the sample, which in turn can be converted into a current. This is the so-called Seebeck effect, the cornerstone of thermoelectric effects. In particular, the effect provides a route to creating work out of a temperature difference. Such thermoelectric engines do not have any movable part and are therefore convenient power sources in various applica
