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 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 ...

Microscopes have long been scientists’ eyes into the unseen, revealing everything from bustling cells to viruses and nanoscale structures. However, even the most powerful optical microscopes have been ...

In 1986, American physicist Arthur Ashkin developed a fascinating tool that could gently pick and move microscopic objects like cells and molecules without touching them. This tool, called optical ...

“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 ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

Probing the vibration of atoms provides detailed information on local structure and bonding that define material properties.

The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.
