"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

A new paper suggests that we could search for photons created by gravitational waves. A specific physical response turns gravitons from these waves into photons of electromagnetism. Scientists believe ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

Atoms inside of an optical cavity exchange their momentum states by "playing catch" with photons. As the atoms absorb photons from an applied laser, the whole cloud of atoms recoil rather than the ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely ...

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

The phenomenon of light slowing down as it passes through a material like glass or air is one of the most fascinating areas of physics, involving a complex interaction between light and materials.
