Ordinarily, crossing light streams (such as shining two flashlights so that they converge) does nothing out of the ordinary. This is because the individual light particles, aka photons, do not ...

For the first time, scientists have watched groups of three photons interacting and effectively producing a new form of light. In results published in Science, researchers suggest that this new light ...

In the push to shrink and enhance technologies that control light, MIT researchers have unveiled a new platform that pushes the limits of modern optics through nanophotonics, the manipulation of light ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.
