The consistent approach to the "atom, nucleus - realistic laser field" interaction is presented and based on the QED and Gell-Mann and Low S-matrix formalism. . The method is applied to studying the multi-photon resonance width and shift in the atom of H in a laser pulse. © 2010 American Institute of Physics. Source

The combined QED perturbation theory formalism and relativistic nuclear mean-field theory are applied to studying the fundamental parameters of the hyperfine, electroweak, parity non-conservation (PNC) interactions in heavy atoms, nuclei. There are firstly predicted the nuclear weak charged for some atoms. © 2010 American Institute of Physics. Source

We analyze theoretically a hybridization type dressing of orbital (i.e., charge) and spin degrees of freedom of excitations captured in semiconductor quantum dot with band phonons and magnons (the latter for magnetic semiconductor surroundings), as a mechanism of dephasing of rapidly excited dot exciton state. Within the Green function approach we derive our previously formulated heuristic general rule for estimation of corresponding dephasing time-rate. The pure dephasing (off-diagonal decoherence) of quantum dot exciton resulting due to this dressing is studied, for both orbital and spin states of the exciton. A significant difference between phonon-induced (for charge) and magnon-assisted (for spin) quantum dot exciton dephasing is indicated as the result of the spin conservation, which leads to the disappearance of the exciton spin pure-dephasing at T = 0 (freezing out of spin dephasing), in contrary to the exciton charge dephasing caused by phonons, which maintains strong even at T = 0. © 2011 World Scientific Publishing Company.

The behavior of the diameter of the coexistence curve in terms of the entropy and the corresponding diameter are investigated. It is shown that the diameter of the coexistence curve in terms of the entropy is sensitive to the change in the character of the rotational motion of the molecule in liquid phase which is governed by the short range correlations. The model of the compressible effective volume is proposed to describe the phase coexistence both in terms of the density and the entropy. © 2011 Elsevier B.V. Source

A uniform quantum energy approach for studying spectra of the multicharged ions in a plasmas and the electron-ion collision cross sections is presented. The approach is based on formally exact QED theory by using the relativistic Dirac Hamiltonian for electron-nuclear and electron-electron potentials, the gauge invariant scheme of generation for the optimal one-quasiparticle representation and the Debye shielding model. The measured and calculated electron-collisional excitation cross sections for Ne-like barium ion for different values of the incident electron energy are presented and analyzed. © 2010 Wiley Periodicals, Inc.
