Researchers at the Ye Lab at JILA (the National Institute of Standards and Technology and the University of Colorado Boulder) and University of Delaware recently created a highly precise optical ...

Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) has developed a strontium optical lattice clock with both frequency ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Optical atomic clocks are the most accurate measuring instruments ever built and are becoming key tools for basic and applied research, for example to test the constancy of natural constants or for ...

…and substances will be identified by mini devices based on metalenses, says VTT Research. A new record in optical-clock absolute frequency measurements. A research team at VTT MIKES, a Helsinki, ...

Highly charged ions are a common form of matter in the cosmos, where they are found, for example, in the sun or other stars. They are so called because they have lost many electrons and therefore have ...
