That “magic” angle had long been suspected to be of special interest in twisted bilayer graphene ... but entirely from their orbital angular momentum—a theorized but never-before-observed ...

They hit their graphene sample with light carrying orbital angular momentum that circulated clockwise ... they still had trouble aligning their twisted light with the sample to observe the current.

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 ...

But what about orbital angular momentum? Normally, that is zero. However, if you can make it non-zero, then you have twisted light. Furthermore, unlike spin momentum which takes on just two values ...

There’s a new kind of twisted light. A rotating “vortex ... Researchers discovered in 1992 that a beam of light could have orbital angular momentum, meaning that the beam twists as it ...

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 ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser ... between light that is twisted clockwise and light that is twisted ...

A beam of “twisted” neutrons with a well-defined orbital angular momentum (OAM) has been created by researchers in Canada and the US. This was done by passing a neutron beam from a nuclear reactor ...

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 ...
