Physicists have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability. Physicists at the ...

The low-energy excited state of thorium-229 (229Th) isotope nucleus has recently gained much attention owing to it being an ideal candidate for ultra-precise nuclear clocks. Building such ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that ...
