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 ...

is one of the world’s leading institutions and has so far realized an impressive range of different optical clocks - including optical single ion clocks and optical lattice clocks. The high level of ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Two further optical and one microwave clock systems of PTB participated in the comparisons: a single-ion ytterbium clock, a strontium lattice clock, and a cesium fountain clock.

Without Katori's custom-made timekeeper, the experiment wouldn't have been possible, as conventional optical lattice clocks are so mammoth in size that just one can fill an entire laboratory.
