Superconductivity-enhanced phonon angular momentum
Natsuki Okada, Philipp Werner, Shintaro Hoshino
We theoretically investigate the properties of phonon angular momentum in the superconducting state, using fulleride compounds in an external magnetic field as a model system. The…

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…
