Attosecond physics hidden in Cherenkov radiation

Autor: Karlovets, D., Chaikovsakaia, A., Grosman, D., Kargina, D., Sizykh, G.

Cherenkov radiation of charged particles moving with superluminal velocities in transparent media is a well-studied phenomenon with a plethora of applications. Its microscopic origins can be traced to the polarization of atomic shells, characterized

Nonstationary Laguerre-Gaussian states vs Landau ones: choose your fighter

Autor: Sizykh, G. K., Chaikovskaia, A. D., Grosman, D. V., Pavlov, I. I., Karlovets, D. V.

Publikováno v: Progress of Theoretical and Experimental Physics, Volume 2024, Issue 5, May 2024, 053A02

Although the widely used stationary Landau states describe electrons with a definite orbital angular momentum (OAM) in a magnetic field, it is the lesser known nonstationary Laguerre-Gaussian (NSLG) states that appropriately characterize vortex elect

Transmission of vortex electrons through a solenoid

Autor: Sizykh, G. K., Chaikovskaia, A. D., Grosman, D. V., Pavlov, I. I., Karlovets, D. V.

Publikováno v: Phys. Rev. A 109, L040201 (2024)

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 their dynamics at a hard-edge boundary between a solenoid and vacuum a

Evolution of the accelerated charged vortex particle in an inhomogeneous magnetic lens

Autor: Baturin, S. S., Grosman, D. V., Sizykh, G. K., Karlovets, D. V.

Publikováno v: Phys. Rev. A 106, 042211 2022

We present a detailed analysis of the capture and acceleration of a non-relativistic charged vortex particle (electron, positron, proton, etc.) with an orbital angular momentum in a field of an axisymmetric electromagnetic lens, typical for a linear

Shifting physics of vortex particles to higher energies via quantum entanglement

Autor: Karlovets, D. V., Baturin, S. S., Geloni, G., Sizykh, G. K., Serbo, V. G.

Publikováno v: Eur. Phys. J. C 83, 372 (2023)

Physics of structured waves is currently limited to relatively small particle energies as the available generation techniques are only applicable to the soft $X$-ray twisted photons, to the beams of electron microscopes, to cold neutrons, or non-rela

Generation of vortex particles via generalized measurements

Autor: Karlovets, D. V., Baturin, S. S., Geloni, G., Sizykh, G. K., Serbo, V. G.

Publikováno v: European Physical Journal C 82(11): 1008 (2022)

The hard X-ray twisted photons and relativistic massive particles with orbital angular momentum -- vortex electrons, muons, protons, etc. -- have many potential applications in high-energy and nuclear physics. However, such states can be obtained so
