Phonon effect of the in-plane oxygen atoms is investigated by numerical exact diagonalizations of the t-J Holstein model. The present study indicate that the breathing vibration mode gives rise to a polaronic effect which yields a broadening of the quasiparticle spectrum, as the one observed in angle-resolved photoemission spectroscopy. © 2006 American Institute of Physics

    The Holstein Molecular Crystal Model is investigated by a strong coupling perturbative method which, unlike the standard Lang- Firsov approach, accounts for retardation effects due to the spreading of the polaron size. The effective mass is calculated to the second perturbative order in any...

    An interacting electron-phonon system is considered within the Extended Holstein model at strong coupling regime and nonadiabatic approximation. It is assumed that screening of an electron-phonon interaction is due to the excess electrons in a lattice. An influence of the screening on the mass...

    The effect of exchange enhancement of electron-phonon interactions in high-temperature superconductor (HTSC) systems is examined and an upper bound is determined for applicability of the quasilinear equations. The spin-phonon interaction in the HTSC phase is described. It is found that if the...
