Source: Physical Review A. 2021. Vol. 103, № 1. P. 012214-1-012214-12
Type: статьи в журналах
Date: 2021
Description:
There is a controversy of how to interpret interactions of electrons with a large spatial coherence with light and matter. When such an electron emits a photon, it can do so either as if its charge we

Description:
A wide variety of emission processes by electron wave packets with an orbital angular momentum ℓhbar, called the vortex electrons, can be influenced by a nonparaxial contribution due to their intrinsi

Description:
The possibilities to accelerate vortex electrons with orbital angular momentum (OAM) to relativistic energies and to produce vortex ions, protons, and other charged particles crucially depend on wheth

Type: статьи в журналах
Date: 2020
Description:
We consider the electron-positron pair production in relativistic heavy ion collisions, in which the produced electron is captured by one of the nuclei resulting, thus, in the formation of a hydrogen-

Description:
Effects of the quantum interference in collisions of particles have a twofold nature: they arise because of
Source: Physical Review A. 2019. Vol. 99, № 4. P. 043824-1-043824-7

Description:
A quantum state of an electron influences its electromagnetic field. If a spatial profile of the electron wave packet is not Gaussian, the particle may acquire additional intrinsic multipole moments,

Description:
The charged wave packets with non-Gaussian spatial profiles are shown to possess intrinsic multipole moments. The magnetic dipole moment and the electric quadrupole moment are found for a wide class o

Description:
We derive a relatively simple and Lorentz-invariant expression for a Wigner function of a paraxial vortex electron described as a Laguerre–Gaussian wave packet.

Description:
A plane-wave approximation in particle physics implies that a width of a massive wave packet σ⊥ is much larger than its Compton wavelength λc=ℏ/mc. For Gaussian beams or for packets with the non-singu

Description:
The potential scattering of electrons carrying non--zero quanta of the orbital angular momentum (OAM) is studied in a framework of the generalized Born approximation, developed in our recent paper by

Description:
A general problem of 2→Nf scattering is addressed with all the states being wave packets with arbitrary phases. Depending on these phases, one deals with coherent states in (3+1) D, vortex particles w
