Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

No theory could explain the slight excess of far-ultraviolet light in the Milky Way until now.

Light that twists as it travels and materials whose internal order is knotted like a pretzel are starting to collide in the lab, and the result is a new class of strange, topological effects. Instead ...

Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most ...

Light and matter can remain at separate temperatures even while interacting with each other for long periods, according to new research that could help scale up an emerging quantum computing approach ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

Strong light–matter coupling has emerged as a transformative concept in modern physics, whereby the interaction between confined electromagnetic fields and material excitations is engineered to yield ...
