QED Corrections in Unstable Vacuum
V. A. Zaytsev, V. A. Yerokhin, C. H. Keitel +1
Self-energy and vacuum polarization effects in quantum electrodynamics (QED) are calculated for the supercritical Coulomb field, where Dirac energy levels become embedded in the ne…
Resonant sequential two-photon ionization of atoms by twisted and plane-wave light
V. P. Kosheleva, V. A. Zaytsev, R. A. Müller +2
We study the resonant sequential two-photon ionization of neutral atoms by a combination of twisted- and plane-wave light within a fully relativistic framework. In particular, the…
Bremsstrahlung from twisted electrons in the field of heavy nuclei
M. E. Groshev, V. A. Zaytsev, V. A. Yerokhin +1
We present a fully relativistic calculation of the bremsstrahlung emitted by twisted electrons propagating in the field of bare heavy nuclei. The electron-nucleus interaction is ac…
Complex scaled relativistic configuration-interaction study of the resonances in helium-like ions: from Boron to Argon
V. A. Zaytsev, I. A. Maltsev, I. I. Tupitsyn +1
Energies and Auger widths of the resonances in He-like ions from boron to argon are evaluated by means of a complex scaled configuration-interaction approach within the framew…
Elastic scattering of twisted electrons by atomic target: Going beyond the Born approximation
V. P. Kosheleva, V. A. Zaytsev, A. Surzhykov +2
The elastic scattering of twisted electrons by neutral atoms is studied within the fully relativistic framework. The electron-atom interaction is taken into account in all orders,…
Analysis of angular momentum properties of photons emitted in fundamental atomic processes
V. A. Zaytsev, A. S. Surzhykov, V. M. Shabaev +1
Many atomic processes result in the emission of photons. Analysis of the properties of emitted photons, such as energy and angular distribution as well as polarization, is regarded…
