Team's bigger and better 'tweezer clock' is super stable

JILA physicists have boosted the signal power of their atomic "tweezer clock" and measured its performance in part for the first time, demonstrating high stability close to the best of the latest generation of atomic clocks.

Trapping nanoparticles with optical tweezers

By exploiting a particular property of light diffraction at the interface between a glass and a liquid, researchers have demonstrated the first optical tweezers capable of trapping nanoscale particles.

A photonic curveball has real-world examples in soccer, baseball

Have you ever been amazed by a curveball goal scored by Diego Maradona, Lionel Messi or Christiano Ronaldo? Then you have—possibly without knowing it—been exposed to the Magnus effect: the fact that spinning objects tend ...

Engineers create micron-scale optical tweezers

In 2018, one-half of the Nobel Prize was awarded to Arthur Ashkin, the physicist who developed optical tweezers, the use of a tightly focused laser beam to isolate and move micron-scale objects (the size of red blood cells). ...

Using air to amplify light

In a promising breakthrough for the future of communications, EPFL researchers have developed a technology that can amplify light in the latest hollow-core optical fibers.

Trapping tiny particles: A versatile tool for nanomanipulation

At just 1/1000th of a millimeter, nanoparticles are impossible to see with the naked eye. But, despite being small, they're extremely important in many ways. If scientists want to take a close look at DNA, proteins, or viruses, ...
