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, ...

Nonthermal and thermal plasmas are used in the industrial, engineering, medical, and research industries. Plasma composition is an important parameter in any plasma process. Using optical emission ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

“Plasma” refers to a gas with a significant proportion of ionized molecules, which produce various excited ions, atoms, and molecules. Electrons liberated from ions and atoms are highly energetic and ...

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 ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1986, American physicist Arthur Ashkin developed a fascinating tool that could gently pick and move microscopic objects like ...

The challenges of terahertz-band components and frequency measurement. How a sophisticated combination of optical and electronic components representing advanced principles are being used to measure ...

In recent years, van der Waals crystals have evolved from scientific curiosities into a versatile platform for exploring novel quantum phases and unconventional nanophotonic phenomena. Their layered ...

Physicists routinely exploit femtosecond light pulses to track the movement of atoms in molecules, and are now developing sources that emit even shorter bursts of X-rays to study and control the ...
