Line Profile Asymmetry in Precision Spectroscopy
A. Anikin, T. Zalialiutdinov, D. Solovyev +1
In this review, we have investigated the asymmetry of the line profile in precision one- and two-photon spectroscopy of hydrogen and helium atoms within the framework of a rigorous…
Thermal corrections for positronium
D. Solovyev, T. Zalialiutdinov, A. Anikin
Thermal corrections, including relativistic effects, for the positronium atom are discussed. The theoretical description of thermal corrections is carried out within the framework…
Analysis of nonresonant effects in the two-photon spectroscopy of helium
T. Zalialiutdinov, A. Anikin, D. Solovyev
In the present paper, we study nonresonant corrections for experimental measurements of the transition frequencies in the helium atom. Having attracted more attention, such effects…

In the present paper, we consider nonresonant corrections to transition frequencies in hydrogen for the experiments based on two-photon spectroscopy. A detailed study…
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…
Proton size from precision experiments on hydrogen and muonic hydrogen atoms
D. Solovyev, T. Zalialiutdinov, A. Anikin
The "proton radius puzzle" was recently solved by reducing the four-standard deviation discrepancy between the results for electronic hydrogen () and muonic hydrogen () atom…
Ultrafast dynamics in normal and Charge Density Wave phase of 2H-NbSe2
A. Anikin, R. D. Schaller, G. P. Wiederrecht +3
We investigate carrier and collective mode dynamics in 2H-NbSe using time-resolved optical pump-probe spectroscopy and compare the results with first-principle calculations. Br…

T. Zalialiutdinov, A. Anikin, D. Solovyev
The thermal two-photon level broadening of the excited energy levels in the hydrogen and H-like helium is evaluated via the imaginary part of thermal two-loop self-energy correctio…
Thermal corrections of lowest order for a helium atom
D. Solovyev, T. Zalialiutdinov, A. Anikin
In this paper the new type of thermal corrections for the helium and helium-like atomic systems are introduced. These are thermal one-photon exchange between the bound electrons an…
Importance of nonresonant corrections for the description of atomic spectra

The process of recombination for the hydrogen atom in the heat bath creating the blackbody radiation is descibed within the frameworks of quantum electrodynamics. For this purpose…
Evidence for breathing-type pseudo Jahn-Teller distortions in the charge density wave phase of 1-TiSe
A. Wegner, J. Zhao, J. Li +5
The charge density wave (CDW) phase in 1-TiSe is investigated using angle resolved photoemission spectroscopy (ARPES) and neutron scattering measurements. Our ARPES results…
