Multipolar ordering in the three-orbital Hubbard model
Naoya Chikano, Shintaro Hoshino, Hiroshi Shinaoka
The ground-state phase diagrams of the three-orbital t2g Hubbard model are studied using a Hartree-Fock approximation. First, a complete set of multipolar order parameters for t2g…
Unconventional Pairing from Local Orbital Fluctuations in Strongly Correlated AC
Changming Yue, Shintaro Hoshino, Akihisa Koga +1
The pairing mechanism in AC is investigated by studying the properties of a three-orbital Hubbard model with antiferromagnetic Hund coupling in the normal and supercondu…
Spin-orbital model for fullerides
Ryuta Iwazaki, Shintaro Hoshino
The multiorbital Hubbard model in the strong coupling limit is analyzed for the effectively antiferromagnetic Hund's coupling relevant to fulleride superconductors with three orbit…
Odd-frequency pairing inherent in Bogoliubov Fermi liquid
Tatsuya Miki, Shun-Ta Tamura, Shoma Iimura +1
The disorder and interaction effects on Bogoliubov-Fermi surfaces with preserved inversion symmetry are studied for a low-energy effective model coupled to bosonic degrees of freed…
Multipole representation for anisotropic Coulomb interactions
Shoma Iimura, Motoaki Hirayama, Shintaro Hoshino
Multipole representation is proposed for the anisotropic Coulomb interactions in solids. Any local interactions can be expressed as the product of two multipole operators, and the…
Generalization of spectral bulk-boundary correspondence
Shun Tamura, Shintaro Hoshino, Yukio Tanaka
The bulk-boundary correspondence in one dimension asserts that the physical quantities defined in the bulk and at the edge are connected, as well established in the argument for el…
