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

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

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 ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Concept of magnetic order-mediated excitonic negative refraction and schematic of the micro-device. Imagine shining a ...

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

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 ...

UD researchers develop optical method to detect magnetic behavior of antiferromagnets, paving the way for advanced computing and quantum technologies Imagine computer hardware that is blazing fast and ...
