This light, called orbital angular momentum light ... The team hit the graphene with twisted light, giving the electrons a “spinning kick.” To make this work, they had to get the light ...

In a new experiment, light beams carrying orbital angular momentum caused electrons in graphene to gain (blue beam ... But still, they had trouble aligning their twisted light with the sample to ...

Abstract: In this paper, a wideband tunable reflectarray consisting of a graphene-based metamaterial structure has been developed to generate an orbital angular momentum (OAM) vortex wave in terahertz ...

Optical beams carrying orbital angular momentum (OAM) attract widespread attention and play an important role in optical data storage, optical communications, quantum information processing, ...

Behind them is the scanning tunnelling microscope that they use to create and study graphene quantum dots ... the magnetic moment of an electron created by its orbital or spin angular momentum). In ...

The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a ...

In groundbreaking research, scientists have created a device that generates twisted neutrons with well-defined orbital angular momentum. For the first time in experimental history, researchers at ...

Here’s how it works. Graphene, one of the world's strongest materials, isn't normally magnetic. But when stacked and twisted, graphene develops a rare form of magnetism, new research finds.

Now a team of researchers at Princeton has looked for the origins of this unusual behavior in a material known as magic-angle twisted bilayer graphene ... angular momentum or "spin," and possible ...
