A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but ...

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, ...

Physicists have recreated the Nobel Prize–winning quantum Hall effect using light, revealing that photons can follow the same ...

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 ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

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 ...

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 ...

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 ...

Starting with Einstein's Theory of Relativity, Physics of Light explores the true nature of light, peers inside the atom, and looks ahead to the most cutting edge theories in physics ...
