Primordiant (Formerly SuperRadiant)

In cavity quantum electrodynamics and particularly superradiance, emitters are typically assumed to be independent, interacting only through light shared via a common mode. Although such photon-mediated interactions lead to a wide range of collective opti

Superradiant atoms can help us measure time more precisely than ever. In a new study, researchers present a new method for measuring the time interval, the second, mitigating some of the limitations that today's most advanced atomic clocks encounter. The

JILA physicists have demonstrated a novel laser design that could be stable enough to improve atomic clock performance a hundredfold and even serve as a clock itself, while also advancing other scientific quests such as making accurate "rulers" for measur

Physicists create a prototype of a very stable, although dim, laser which could improve atomic clocks and equipment, such as GPS, which rely on them.
