Complex-scaled ab initio QED approach to autoionizing states

Autor: Vladimir Shabaev, Vladimir Zaytsev, Aleksei Malyshev

Ab initio method based on a complex-scaling approach and aimed at a rigorous QED description of autoionizing states is worked out. The autoionizing-state binding energies are treated nonperturbatively in $\alpha Z$ and include all the many-electron Q

Model-QED operator for superheavy elements

Autor: Vladimir Shabaev, Ilya Tupitsyn, Vladimir Yerokhin, Dmitry Glazov, Vladimir Zaytsev, Aleksei Malyshev

Publikováno v: Physical Review A. 106

The model-QED-operator approach [Phys. Rev. A 88, 012513 (2013)] to calculations of the radiative corrections to binding and transition energies in atomic systems is extended to the range of nuclear charges $110 \leqslant Z \leqslant 170$. The self-e

Particle Production in Strong Electromagnetic Fields and Local Approximations

Autor: Denis Sevostyanov, Vladimir Shabaev, Ivan Aleksandrov

Publikováno v: Symmetry; Volume 14; Issue 11; Pages: 2444

We investigate the phenomenon of electron–positron pair production in intense external backgrounds within the strong-field regime. We perform nonperturbative calculations by solving the quantum kinetic equations, and obtain the momentum distributio

Bremsstrahlung from twisted electrons in the field of heavy nuclei

Autor: Vladimir Shabaev, Artem Zaitsev, Vladimir Yerokhin, Maksim Groshev, Vladimir Zaytsev

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 accounted for to all orders in the nuclear binding strength parameter $\
