  • Electron - phonon interaction in strongly correlated systems. Acoustical phonon case 
    DIGOR, D. F.; DOHOTARU, L. A.; ENTEL, P.; MOSKALENKO, V. A.; VLADIMIR, M. I. (Academy of Sciences of Moldova, 2005)
    We investigate the interaction of strongly correlated electrons with acoustical phonons in the frame of Hubbard-Holstein model. The electron-phonon interaction and on-site Coulomb repulsion are considered to be strong. ...
  • Spin density waves and superconductivity in strongly correlated electron systems 
    DIGOR, D. F.; DOHOTARU, L. A.; ENTEL, P.; MOSKALENKO, V. A.; VLADIMIR, M. I. (Academy of Sciences of Moldova, 2005)
    A special diagram technique recently proposed for strongly correlated electron systems is used to study the peculiarities of a spin-density-wave (SDW) in competition with superconductivity. This method allows to formulate ...
