Physicists reveal non-reciprocal flow around the quantum world

A pair of theoretical physicists, from the University of Exeter (United Kingdom) and the University of Zaragoza (Spain), have developed a quantum theory explaining how to engineer non-reciprocal flows of quantum light and ...

Unravelling the knotty problem of the sun's activity

A new approach to analyzing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, ...
