Nuclear-size correction to the one-loop self-energy in hydrogenlike ions
Ping Yang, Aleksei V. Malyshev, Aleksandr N. Kochnev +4
The nuclear-size effect on both diagonal and off-diagonal one-loop self-energy matrix elements is considered for hydrogenlike ions with , , , and . Specifically,…
Quadratic Zeeman effect in light boron-like ions
V. A. Agababaev, A. V. Volotka, D. A. Glazov +3
The quadratic Zeeman effect is calculated for the ground state of light boron-like ions in the range of nuclear-charge numbers . The calculations are perform…
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…
Schwinger pair production in counterpropagating laser pulses: Identifying volume factors
A. G. Tkachev, I. A. Aleksandrov, V. M. Shabaev
We investigate the nonperturbative process of vacuum pair production in a combination of two counterpropagating linearly polarized laser pulses of a finite spatial extent. By means…
Schwinger particle production: Rapid switch off of the external field versus dynamical assistance
I. A. Aleksandrov, D. G. Sevostyanov, V. M. Shabaev
We consider the process of electron-positron pair production in the presence of strong electric backgrounds being rapidly switched on and off and examine the total particle yield.…
