Self-energy corrections to the ionization energies in sodium-like ions: comparison of the \textit{ab initio} QED and model-QED-operator approaches
P. Yang, A. V. Malyshev, E. A. Prokhorchuk +3
Calculations of the self-energy corrections to ionization energies of the , , and states in sodium-like ions with nuclear-charge numbers , , …
QED effects in quadratic Zeeman splitting in highly charged hydrogen-like ions
V. A. Agababaev, E. A. Prokhorchuk, D. A. Glazov +3
We present ab initio calculations of one-electron quantum electrodynamical corrections to the second-order Zeeman splitting for the , , and states in…
Convergence-acceleration approach to partial-wave expansion of two-electron self-energy contributions to the Lamb shift
A. V. Malyshev, E. A. Prokhorchuk, V. M. Shabaev
Methods of bound-state QED that treat the self-energy contributions to the Lamb shift within the partial-wave expansion usually face the problem of slow convergence of the latter.…
Orbital collapse and dual states of the electrons in superheavy elements
I. I. Tupitsyn, I. M. Savelyev, Y. S. Kozhedub +5
The problem of orbital collapse of the and electrons in atoms of superheavy elements (SHE) is considered. Previously, the presence of the orbital collapse was established…
