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 …

Quantum fluid (or hydrodynamic) models provide an attractive alternative for the modeling
and simulation of the electron dynamics in nano-scale objects. Compared to more standard …

In situ generation of a high-energy, high-current, spin-polarized electron beam is an
outstanding scientific challenge to the development of plasma-based accelerators for high …

High-flux polarized particle beams are of critical importance for the investigation of spin-
dependent processes, such as in searches of physics beyond the standard model, as well …

Here, we demonstrate the radiative polarization of high-energy electron beams in collisions
with ultrashort pulsed bichromatic laser fields. Employing a Boltzmann kinetic approach for …

The acceleration of polarized electrons and protons in strong laser and plasma fields is a
very attractive option to obtain polarized beams in the GeV range. We investigate the …

Completely depolarizing channels are often regarded as the prototype of physical processes
that are useless for communication: any message that passes through them along a well …

High-energy spin-polarized electron, positron, and γ-photon beams have many significant
applications in the study of material properties, nuclear structure, particle physics, and high …

We present a setup for highly polarized proton beams using two parallel propagating laser
pulses that have a carrier envelope phase difference of π. This mechanism is examined …

The acceleration of polarized electrons, positrons, protons and ions in strong laser and
plasma fields is a very attractive option for obtaining polarized beams in the multi-mega …
