Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes ...

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. — ...

In 1845, Michael Faraday discovered what’s known today as the Faraday Effect—which describes how light and electromagnetism are related. A new study revealed that the magnetic component of light ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

(a) Weyl magnet: schematic diagram of a crystal of cobalt-manganese-gallium Heusler alloy (Co 2 MnGa). (b) Light-induced terahertz waves. Terahertz waves are being intensely studied by researchers ...

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...
