Dark matter is one of the biggest mysteries in science. Astronomers believe it makes up most of the matter in the universe, yet no one has ever directly seen it. It does not reflect, emit, or absorb ...

An international team of researchers has forced light to replicate the quantum Hall effect, a Nobel Prize–winning phenomenon ...

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, ...

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

In condensed matter physics, things can get pretty weird. When temperatures get close to absolute zero, it is possible to put matter in a state called supersolid, a crystal that can flow without ...

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 ...

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

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

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 ...

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 ...

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