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 ...

The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has ...

Our research focuses on the development of optical clocks using ultracold atomic systems. By tightly confining ytterbium in the ideal potential of a magic-wavelength optical lattice, the lattice clock ...

Accurate frequency measurements of a narrow optical clock transition in 171 Yb atoms trapped in an optical lattice establish this system as a serious contender in the quest to develop increasingly ...

The invention – called the optical lattice clock – is a thousand times more accurate than cesium atomic clocks used for international timekeeping and is a contender for redefining how long a ...

Optical lattice clocks have previously been installed in Tokyo's famous Skytree to test the general theory of relativity, which states that "time flows more slowly in places with strong gravity." ...

A Japanese analysis equipment maker has started selling a type of clock said to be the world's most precise. The optical lattice clock was developed by a team led by University of Tokyo Professor ...

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.

Optical lattice clocks have previously been installed in Tokyo's famous Skytree to test the general theory of relativity, which states that "time flows more slowly in places with strong gravity".

It is about one hundred times more precise than the traditional cesium atomic clocks The device measures time by using the optical transition of atoms confined in standing waves of light.
