Аннотация: The t-t'-t"-J* model of electrons interacting with three phonon modes (breathing, apical breathing, and buckling) is considered. The wave-vector dependence of the matrix elements of the electron-phonon interaction leads to opposite contributions to the pairing potential with the d(x2-y2) symmetry: the buckling mode facilitates elecПоказать полностьюtron pairing, while the breathing mode suppresses it. As a result, the critical temperature of La2-xSrxCuO4 that is associated with the magnetic mechanism is lowered when phonons are taken into account.
