Theoretical Design of Effective Multilayer Optical Coatings Using Oxyhydride Thin Films
E. Strugovshchikov, A. Pishtshev, S. Karazhanov
Rare-earth metal oxyhydride compositions are currently attracting increasing attention to develop materials with unusual optical responses. Herein, using computer simulations of th…
Experimental studies of thorium ions implantation from pulse laser plasma into thin silicon oxide layers
P. V. Borisyuk, E. V. Chubunova, Yu. Yu. Lebedinskii +7
We report the results of experimental studies related to implantation of thorium ions into thin silicon dioxide by pulsed plasma fluxes expansion. Thorium ions were generated by la…
FeAs formation and electronic nematic ordering: Analysis in terms of structural transformations
A. Pishtshev, P. Rubin
By combining DFT-based computational analysis and symmetry constraints in terms of group-subgroup relations, we analysed the formation of the native crystalline structure of loelli…
Excitons in \ce{Mg(OH)2} and \ce{Ca(OH)2} from \textit{ab initio} calculations
A. Pishtshev, S. Zh. Karazhanov, M. Klopov
By using \textit{ab initio} calculations with the HSE06 hybrid functional and GW approximation combined with numerical solution of the Bethe Salpeter equation (GW-BSE) we predict t…
Assessing structural bonding aspects of multiband superconductors through impurity-induced local lattice distortions: a case study on MgB2
Aleksandr Pishtshev, Mihhail Klopov
We report the results of an ab initio modeling of substitutional impurities such as zinc, copper and zirconium ions incorporated into the magnesium sublattice of MgB2. The goal of…
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Aleksandr Pishtshev
We estimate the contribution of the long-wavelength el-TO-ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytic…
