Generation of Deep Ultraviolet Optical Vortices via Amplitude and Phase Spiral Zone Plates
A. S. Dyatlov, M. A. Nozdrin, A. N. Sergeev +3
We present the development and experimental implementation of diffractive optical elements designed to generate optical vortices in the deep ultraviolet range (from 260 to 266 nm).…
Diffraction by Circular and Triangular Apertures as a Diagnostic Tool of Twisted Matter Waves
Maksim Maksimov, Nikita Borodin, Daria Kargina +2
We study diffraction of twisted matter waves (electrons and light ions carrying orbital angular momentum by circular and triangular apertures. Withi…
Studying highly relativistic vortex-electron beams by atomic scattering
V. K. Ivanov, A. D. Chaikovskaia, D. V. Karlovets
We explore the opportunities of using electron scattering by screened Coulomb potential as a tool to retrieve properties of the relativistic vortex beams of electrons, such as thei…
Transmission of vortex electrons through a solenoid
G. K. Sizykh, A. D. Chaikovskaia, D. V. Grosman +2
We argue that it is generally nonstationary Laguerre-Gaussian states (NSLG) rather than the Landau ones that appropriately describe electrons with orbital angular momentum both in…
