Symmetry-breaking perturbations in the Jahn-Teller-Hubbard model
Natsuki Okada, Tatsuya Miki, Yusuke Nomura +2
We study the effect of symmetry-breaking perturbations in the multiorbital Hubbard model coupled to anisotropic Jahn-Teller phonons, which is relevant for the description of fuller…

Weak coupling approach to magnetic and orbital susceptibilities for superconducting states in multiorbital electron-phonon coupled model
Natsuki Okada, Tatsuya Miki, Shintaro Hoshino
Alkali-doped fullerides are molecular-based superconductors with multiple active orbitals. In this paper, using the Eliashberg theory with the retardation effect of Jahn-Teller pho…
