Local correlation effects on the s+-- and s++-wave superconductivities mediated by magnetic and orbital fluctuations in the 5-orbital Hubbard model for iron pnictides
Jun Ishizuka, Takemi Yamada, Yuki Yanagi +1
We investigate the electronic state and the superconductivity in the 5-orbital Hubbard model for iron pnictides by using the dynamical mean-field theory in conjunction with the Eli…

Metal-insulator transition and superconductivity in the two-orbital Hubbard-Holstein model for iron-based superconductors
Takemi Yamada, Jun Ishizuka, Yoshiaki Ōno
We investigate a two-orbital model for iron-based superconductors to elucidate the effect of interplay between electron correlation and Jahn-Teller electron-phonon coupling by usin…
