A prehistoric climate feedback loop

Against the backdrop of a rapidly warming planet, the need to better understand the nature and long-term impact of positive climatic feedback loops — processes that accelerate the effects of warming — becomes critically important.

A quantum pump without the crank

Physicists 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 path to…
