When a crowd becomes especially big and dense, like at a pilgrimage or a concert, things can get dangerous fast. A Spanish researcher is using physics to understand how they move, and hopefully, how ...

Applied physicists have created a photon router that could plug into quantum networks to create robust optical interfaces for noise-sensitive microwave quantum computers. Applied physicists at the ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...

After Russia invaded Ukraine in February 2022, the International Union of Pure and Applied Physics (IUPAP), then celebrating its 100th anniversary, issued a statement condemning the war. It noted its ...

A soccer match has just ended and a river of fans pours out of Pamplona's massive soccer stadium. When a mass of people like this start to move, the laws of physics — rather than free will — begin to ...

Beams of light that can be guided into corkscrew-like shapes called optical vortices are used today in a range of applications. Pushing the limits of structured light, Harvard applied physicists in ...
