What Katori proposed in the optical lattice clock was to measure the transition in energy states among a batch of neutral strontium atoms, laser-cooled and trapped into a lattice formed by laser ...

JILA's experimental atomic clock based on strontium atoms held in a lattice of laser light is the world's most precise and stable atomic clock. The image is a composite of many photos taken with ...

The world’s most accurate commercially available clock went on sale this week… and it doesn’t even tell the time. And since the newly available strontium optical lattice clock will set you ...

According to the Kyoto-based company, its compact optical lattice timepiece, released on March 5, is a kind of strontium atom clock. Using a specialized laser beam called the “magic wavelength ...

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 research group led by Professor Hidetoshi Katori, an inventor of the optical lattice clock, developed the two optical lattice clocks, which perform the high- precision spectroscopy of strontium ...

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 ...

Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy, with relative uncertainties as low as one part in 10²⁰. But a new kind of clock ...
