A quantum pump without the crank - EurekAlert

Physicists at ETH Zurich demonstrate how atoms can be pumped through a synthetic crystal without having to apply any external periodic driving. These experiments combine several key aspects of quantum many-​body physics in unexpected ways, thus paving a novel…
