In recent years, physicists have been trying to attain the control of chemical reactions in the quantum degenerate regime, where de Broglie wavelength of particles becomes comparable to the spacing between them. Theoretical ...
(Phys.org) —The National Institute of Standards and Technology (NIST) is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official U.S. time in ways that will ...

A team of researchers at the JILA, National Institute of Standards and Technology at the University of Colorado has found a way to use an atomic clock to demonstrate a principle of general relativity. The team has published ...
(PhysOrg.com) -- GPS is getting an upgrade costing $8 billion (US), which aims to increase the system's accuracy, improve its reliability, and make the technology even more widespread.
Atomic clocks are a class of clocks that leverage resonance frequencies of atoms to keep time with high precision. While these clocks have become increasingly advanced and accurate over the years, existing versions might ...
(PhysOrg.com) -- For almost sixty years, the world has considered the atomic clock the gold standard for keeping time. Its accuracy is such that it drifts by only about four seconds over a period of about thirteen and a half ...
