| 内容記述 | We study the electronic states and the superconductivity in the two-dimensional 16-band d-p model coupled with A1g, B1g, and Eg local phonons and obtain the rich phase diagram including the magnetic-, charge-, and orbital-ordered phases on the parameter plane of the Coulomb and electron-phonon interactions. When the electron-phonon interaction is dominant, the charge fluctuations induce the s++-wave superconductivity, while when the Coulomb interaction is dominant, the magnetic fluctuations induce the s±wave superconductivity. Remarkably, the orbital fluctuations are enhanced due to the cooperative effects of the Coulomb and electronphonon interactions and induce the s++-wave and the nodal s±wave superconductivities. | |||||
