Orbital Angular Momentum (OAM): The quantised component of angular momentum arising from the spatial distribution and helical phase structure of an electron beam.

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...

Electron waves that carry orbital angular momentum (OAM) are characterized by a quantized and unbounded magnetic dipole moment parallel to their propagation direction. When interacting with ...

Orbital angular momentum monopoles have been the subject of great theoretical interest as they offer major practical ...

The orbital angular momentum is one of the fundamental quantum numbers of the electron, similar to spin, which describes the apparent rotation of the electron. However, OAM is rarely observable in ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

A research team succeeds in solving a decade-old physical puzzle: the question of the fate of angular momentum during the ultrafast demagnetization of nickel crystals by laser light.

Orbital-angular-momentum-encoded diffractive networks for object classification tasks ... OAM can carry spatial information such as an object’s position, arrangement, or structure.

Desirable among these textures, is a spherical collection of orbital angular momentums, with axis pointing to the centre, dubbed the orbital angular momentum monopole. These could exist in two states, ...

New link between crystal structure and electron "Our results show that the structure of the crystal directly influences the angular momentum of the electrons—an effect that we were able to ...
