Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to ...

Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall effect that was previously seen only in electrons confined to ultra-thin ...

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 ...

Physicists have detected laser-assisted electron scattering using circularly polarized light for the first time, revealing new ways to probe atomic-scale chirality.

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called “bands” and the space between them, the forbidden energies, are known as “band-gaps”. Both ...
