The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists have now discovered that in certain ...

The simplest class of light field that can carry orbital angular momentum (OAM) is an optical vortex. An optical vortex is a beam of light whose phase varies in a corkscrew-like manner along the ...

Aug. 23, 2021 — Bilayer graphene with one of the two layers twisted displayed unique resonant electronic behavior. Understanding how electrons move in such 2-D materials could shed light on how ...

An idea to vastly increase the carrying capacity of radio and light waves has been called into question. The "twisted light" approach relies on what is called light's orbital angular momentum, which ...
