Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

In order to address the present difficulty in experimentally generating the relativistic
Laguerre-Gaussian laser, primarily due to damage caused to optical modulators, a high …

Low-intensity light beams carrying orbital angular momentum (OAM), commonly known as
vortex beams, have garnered significant attention due to promising applications in areas …

Ultra-short brilliant γ-rays have many potential applications in astrophysics, nuclear physics,
and ultra-fast science. However, attosecond γ-ray beams with energy above 100 MeV are …

X/γ-rays have many potential applications in laboratory astrophysics and particle physics.

A scheme to produce mega-electron-volt-(MeV) level gamma rays with a high level of
brilliance, a small divergence angle, and controllable angular momentum from Laguerre …

By using three-dimensional particle-in-cell simulations, we investigate the dynamics of
ultraintense Laguerre–Gaussian (LG) laser pulses interacting with a wire target. When a …

The general formula for probability to record a twisted photon produced by a charged
particle moving in an inhomogeneous isotropic dispersive medium is derived. The explicit …

We study theoretically and numerically the Raman backscattering process of a laser beam
carrying an orbital angular momentum. By expanding the electromagnetic and electrostatic …
