In this work, detection probability of the orbital angular momentum (OAM) states of the Bessel-Gaussian (BG) and Laguerre-Gaussian (LG) beams passing through a plasma sheath turbulence (PST) are theoretically investigated. For this purpose, OAM-spect

Abstract We explore the propagation of structured vortex laser beams-shaped light carrying orbital angular momentum (OAM)-through complex multiple scattering medium. These structured vortex beams consist of a spin component, determined by the polariz

Abstract Extreme ultraviolet (EUV) light is difficult to focus due to strong absorption of most materials. Photon sieves (PS), rather than Fresnel zone plates (FZP), can focus EUV to smaller spot and suppress the higher orders of secondary maxima by

In this article, we highlight that the interaction potential confining Dirac particles in a box must be invariant under the charge conjugation to avoid the Klein paradox, in which an infinite number of negative-energy particles are excited. Furthermo
