By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a ...

A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of ...

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 ...

While it's no replacement for either computer, the new device is a powerful alternative for addressing some very practical ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

You can tell a lot about a material based on the type of light shining at it: Optical light illuminates a material's surface, ...

A course offered at the University of Wisconsin has long been connecting seemingly unrelated fields — the sciences and arts — into an interdisciplinary education. Physics 109 — Physics in the Arts — ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

There’s about $35M up for grabs if your circuits can beat today’s limits It's no lightweight matter. DARPA is putting about $35 million in total funding on the table in the hope that it will spur ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...
