(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 ...

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 ...
