Electron vortices are electron beams that carry orbital angular momentum, meaning the electrons move not only in their propagation direction but also rotate in a vortex-like manner.

The orbital angular momentum (OAM) carried by the vortex beams is considered as a new set forming the basis of carrier signals that is different from amplitude, phase, polarization, and frequency.

A pattern of rings reveals the presence of vortex beams of atoms and molecules. Each doughnut shape corresponds to a beam of helium atoms with a different angular momentum. Two hard-to-see circles ...

Since the dynamic signature of vortex beams is determined by the OAM mode, the OAM mode measurement is one of the crucial tasks which is prior to the applications of vortex beams.

The research, titled "Orbital angular momentum control of strong-field ionization in atoms and molecules," is published in Nature Communications.

To analyse the beam’s total angular momentum, the researchers rotated the orbital and spin components by different amounts: 180° and 90°, respectively. This enabled them to sort photons into two ...

Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams.

The orbital angular momentum given to atoms inside the spiraling beam also changes the quantum mechanical "selection rules" that determine how the swirling atoms will interact with other particles ...
