The structure — a square overhead loop connecting two square panels — increases the incoming radio signal, or electric field, applied to the gaseous atoms in
After extensive study in the laboratory and two real-world environments, NIST results confirmed that the main signal path — over a clear “line of sight” between
JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever
In efforts to limit the spread of disease while preserving privacy, an interdisciplinary research team at the National Institute of Standards and Technology
The nation should bolster research and development of systems that distribute accurate time via fiber-optic cable and radio as part of the effort to back up GPS
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested “Fermi sea,” thus keeping atoms in a high-energy state, or
