New observation could provide way to increase the strength of interaction between light and matter, eventually leading to smaller lasers and other improved photonic technologies UNIVERSITY PARK, Pa. — ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction ...

Scientists have created the world's thinnest magnet, just one atom thick, which could revolutionize computer memory in the ...

(Nanowerk News) Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively “feel” a ...
