Yuri Ralchenko led one of the oldest teams at the National Institute for Standards and Technology. The fate of some ...

The key innovation of our propulsion concept is the unique coupling of a neutral particle beam with a laser beam, a scheme which nearly eliminates thermal expansion and diffraction during beam ...

Researchers propose a new approach to making qubits, the basic units in quantum computing, and controlling them to read and write data. The method is based on measuring and controlling the spins of ...

Atomic analogue: when a beam of light is shone into a water droplet, the light is trapped inside. (Courtesy: Javier Tello Marmolejo) Light waves confined in an evaporating water droplet provide a ...

Physicists have, for the first time, now built a theoretical construct of beams made of twisted atoms. These findings by Armen Hayrapetyan and colleagues at Ruprecht-Karls-University Heidelberg in ...

The tractor beam is a long-serving staple of sci-fi, but now Australian researchers have created a new type of real-world version. While it won't exactly be capturing enemy spaceships anytime soon, ...

The 'Gamma Factory initiative' -- an international team of scientists -- is currently exploring a novel research tool: They propose to develop a source of high-intensity gamma rays using the existing ...
