Nonlocality of the effective interaction of the radiation field with a strong external electromagnetic field

Gainutdinov R.; Khamadeev M.; Mutygullina A. (2008)

We investigate the problem of nonlocality of the effective interaction of the radiation field with a strong external field. It is shown that the use of a Lagrangian or Hamiltonian interaction density with a nonlocal ...
Nonlocality of the NN interaction in an effective field theory

Gainutdinov R.; Mutygullina A. (2002)

We investigate low energy nucleon dynamics in the effective-field theory (EFT) of nuclear forces. In leading order of the two-nucleon EFT we show that nucleon dynamics is governed by the generalized dynamical equation with ...
Nonperturbative effects in self-energy functions of quantum dots coupled to an acoustic phonon reservoir

Gainutdinov R.; Blum D.; Mutygullina A. (2018)

© Published under licence by IOP Publishing Ltd. The problem of description of the strong interaction of a quantum dot (QD) with an acoustic phonon reservoir is discussed. It is shown that the generalized dynamical equation ...
Precision laser spectroscopy and the proton radius puzzle

Gainutdinov R.; Mutygullina A. (2014)

The problem of the discrepancy between the proton radius values obtained via spectroscopy of ordinary and muonic hydrogen is discussed. It is shown that there is a flaw in the standard theory of quantum electrodynamics ...
Quantum fluctuations in semiconductor quantum dots and their contributions to the self-energy functions of exciton states

Mutygullina A.; Khamadeev M.; Blum D.; Shirdelhavar A. (2017)

Influence of quantum fluctuations in a system consisting of a quantum dot and the reservoir of acoustic phonons on processes in which the quantum dot takes part is investigated. Under some conditions this influence is shown ...
Self-energy function of quantum-dot states and resonance fluorescence

Gainutdinov R.; Khamadeev M.; Mohebbifar M.; Mutygullina A. (2014)

© Published under licence by IOP Publishing Ltd. We investigate the energy dependence of self-energy functions of quantum-dot states that describe the interaction of quantum dots with vacuum. It is shown that the variation ...
Suppression of transition dipole moments in radioactive atoms

Gainutdinov R.; Petrova A.; Mutygullina A. (2017)

Optical emission from radioactive atoms is investigated. It is shown that the radioactivity of the central nucleus results in the suppresion of the optical transition dipole moment in the corresponding atom. The situations ...
The bound states problem in quantum electrodynamics and vacuum polarization effects in muonic atoms

Vasil'ev A.; Gainutdinov R.; Mutygullina A.; Salakhov M. (2010)

Quantum electrodynamic bound states in strong electromagnetic fields are considered. It is shown that the dynamics of the system can not be described completely in the adiabatic S-matrix approach. Vacuum polarization effects ...
The generalized dynamical equation and the vacuum polarization effect in hydrogenlike atoms

Vasil'ev A.; Gainutdinov R.; Mutygullina A. (2012)

Based on the generalized dynamical equation, vacuum polarization effects are studied within the scope of the bound state theory in quantum electrodynamics. We find a vacuum-polarization correction to the Lamb shift for the ...
The influence of the nuclear self energy function on the spectral lines of atoms with unstable nuclei

Gainutdinov R.; Mutygullina A.; Petrova A. (2016)

Optical emission from atoms with radioactive nuclei is investigated. The self energy function of the unstable nucleus is constructed. A new arbitrary parameter characterizing the nuclear interaction is introduced. The ...
Tunneling-induced self-energy shift of energy levels of a quantum dot

Gainutdinov R.; Khamadeev M.; Mohebbifar M.; Mutygullina A. (2015)

© Published under licence by IOP Publishing Ltd. The self-interaction of a quantum dot tunnel with Coulomb interaction coupled to two noninteracting leads is investigated. The self-energy function describing this interaction ...
Unstable electron states in the field of a superheavy nucleus

Gainutdinov R.; Mutygullina A.; Petrova A.; Salakhov M. (2010)

The problem of bound states in supercritical fields is considered. The shape of the energy distribution for the |1s〉 electron bound state embedded in the lower continuum is obtained within the generalized quantum dynamics ...
Unstable vacuum and spectrum of atoms with a superheavy nucleus

Gainutdinov R.; Mutygullina A.; Khamadeev M.; Petrova A. (2013)

We show that the light spectra of atoms with a superheavy nucleus may be important for our understanding of the processes in supercritical fields. The shape is obtained of a spectral line emitted by an atom with a superheavy ...
