The orbital angular momentum (OAM) carried by the vortex ... structure distribution of a partially coherent Laguerre Gaussian beam in the far field consists of a series of concentric dark ring ...

In particular, modes of structured light carrying orbital angular momentum (OAM ... a flexible platform to generate VVBs and Gaussian beams, and investigated their propagation through a medium ...

Is it possible to drive nanoparticles to orbit below the light diffraction limit using a Gaussian ... the spin angular momentum of light is converted into the orbital angular momentum of particles ...

Be warned, the idea of orbital angular momentum in light is a bit bizarre. First, let's start with an ordinary light beam that is circularly polarized. In this case, if the light field is ...

Orbital Angular Momentum (OAM), can be controlled. This newfound control of neutron OAM states means that researchers can now use neutron OAM beams to see inside materials that optical ...

Orbital angular momentum rotates a light beam’s wavefront around its propagation axis, giving it a corkscrew shape. Inspiration for the work, says Eastham, came from celebrations of the 200th ...

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.

A new twist on transmission electron microscopy (TEM) could enable the technique to unlock even more secrets on the nanoscale. Researchers in the US have produced a helical-shaped beam of electrons ...

The research showcases how a type of light called the orbital angular momentum (OAM ... OAM is defined as a type of structured light beams, which are light fields which have a tailored spatial ...
