The new method, which uses quantum dots, performs as well as or better than current infrared light sources while being much ...

Dark matter is one of the biggest mysteries in science. Astronomers believe it makes up most of the matter in the universe, ...

In physics, the classical "Hall effect," discovered in the late 19th century, describes how a transverse voltage is generated ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

By squeezing terahertz light beyond its usual limits, researchers have exposed hidden quantum "jiggles" inside a superconducting material. The kind of light you use can reveal very different things ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

An international team of physicists has cooked up with a new theory that could allow for objects to travel faster than the speed of light — and while they say it wouldn’t technically violate the laws ...

Scientists captured the first images of the Terrell-Penrose effect, showing objects near light speed appear rotated rather than compressed in photos.

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...
