A new publication from Opto-Electronic Advances, 10.29026/oes.2024.240001 discusses robust detection technology of orbital angular momentum of partially coherent vortex light fields in complex ...

Fast keying and mode switching exploiting the orbital angular momentum of light are sought after in optical communications and quantum key distribution for larger transmission capacity and higher ...

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

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.

Nowadays, the generation and application of optical vortices have been extended to the regime of intense-light-matter interaction. The characterization of the orbital angular momentum (OAM) of ...

Such collisions are well-understood for normal particle beams, but not for those with orbital angular momentum. Similar vortex beams made with protons might also serve as a method for probing the ...

In 1992, Allen and others discovered that light beams could carry quantized orbital angular momentum, laying the theoretical foundation for electron vortex technology. Electrons, as charged particles, ...

Researchers discovered in 1992 that a beam of light could have orbital angular momentum, meaning that the beam twists as it propagates forward, with each photon circling around the centre of the beam.

Orbital angular momentum rotates a light beam’s wavefront around its propagation axis, giving it a corkscrew shape. Individually, the two types of angular momentum come in multiples of the reduced ...
