Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions bend.

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles. Microscopic crystals in tantalum disulfide ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where ...

Light is a phenomenon that happens daily. It is a physical occurrence. We use lamps to read, we use headlights to drive in unsafe situations, we use it to grow plants, and we use it as a form of ...

Light does more than illuminate the world—it can also push and twist matter. It was back in the 1870s that James Clerk ...
