Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

A self-configuring photonic chip separates partially coherent light into distinct optical modes that emerge through different ...

In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light ...

Last summer, Stanford University researchers delivered patterns of light to a mouse’s brain that generated a hallucination intense enough to influence the animal’s behavior. The experiment was ...

Newswise — At the upgraded Advanced Photon Source (APS), a powerful X-ray light source at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, new analysis capabilities are changing how ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with the aim of making graphene, rather than light. They succeeded, and they ...

In recognition of the International Day of Light (@IDL2019) on May 16, the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) is highlighting how scientists use light in ...
