Angular correlations in two-photon spectroscopy of hydrogen
A. Anikin, T. Zalialiutdinov, D. Solovyev
In the present paper, we consider nonresonant corrections to transition frequencies in hydrogen for the experiments based on two-photon spectroscopy. A detailed study…
Damped perturbations of systems with centre-saddle bifurcation
Oskar Sultanov
An autonomous system of ordinary differential equations in the plane with a centre-saddle bifurcation is considered. The influence of time damped perturbations with power-law asymp…
Relativistic corrections to the thermal interaction of bound particles
D. Solovyev, T. Zalialiutdinov, A. Anikin
This paper discusses relativistic corrections to the thermal Coulomb potential for simple atomic systems. The theoretical description of the revealed thermal corrections is carried…
VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
A heuristic guide to evaluating triple-sums
Eric T. Mortenson
Using a heuristic that relates Appell--Lerch functions to divergent partial theta functions one can expand Hecke-type double-sums in terms of Appell--Lerch functions. We give examp…
Total yield of electron-positron pairs produced from vacuum in strong electromagnetic fields: validity of the locally constant field approximation
D. G. Sevostyanov, I. A. Aleksandrov, G. Plunien +1
The widely-used locally constant field approximation (LCFA) can be utilized in order to derive a simple closed-form expression for the total number of particles produced in the pre…
