Optical vortices are currently one of the most intensively studied topics in optics. These light
beams, which carry orbital angular momentum (OAM), have been successfully utilized in the …

Vortex light beams are structures of the electromagnetic field with a spiral phase ramp
around a point-phase singularity. These vortices have many applications in the optical …

Photons have fixed spin and unbounded orbital angular momentum (OAM). While the former
is manifested in the polarization of light, the latter corresponds to the spatial phase …

Extreme-ultraviolet vortices may be exploited to steer the magnetic properties of
nanoparticles, increase the resolution in microscopy, and gain insight into local symmetry …

In this study, for the first time, a theoretical investigation is carried out on the persistent orbital
charge-currents (cc) and induced magnetic field (imf) of Li and Na atom compressed by …

With wavelength tunability, free-electron lasers (FELs) are well-suited for generating orbital
angular momentum (OAM) beams in a wide photon energy range. We report here the first …

The formulation of the interaction of matter with singular light fields needs special care. In a
recent article [GF Quinteiro, Phys. Rev. A 91, 033808 (2015) PLRAAN 1050-2947 …
