Rubidium atoms on China’s Tiangong space station fell with the same acceleration, upholding a cornerstone of Einstein’s ...

A cloud of ultracold atoms has provided a new experimental connection between two theories that physicists still cannot fully reconcile. Researchers have directly measured the quantum phase acquired ...

Scientists at the University of Ulm, the University of Oxford, and the Ben-Gurion University of the Negev collaborated to conduct experiments that for the first time showed that a falling quantum ...
