Wide applicability of high pairing originating from coexisting wide and incipient narrow bands in quasi one dimension
Karin Matsumoto, Daisuke Ogura, Kazuhiko Kuroki
We study superconductivity in the Hubbard model on various quasi-one-dimensional lattices with coexisting wide and narrow bands originating from multiple sites within a unit cell,…

Possible high- superconductivity due to incipient narrow bands originating from hidden ladders in Ruddlesden-Popper compounds
Daisuke Ogura, Hideo Aoki, Kazuhiko Kuroki
We introduce a concept of hidden ladders for the bilayer Ruddlesden-Popper type compounds: While the crystal structure is bilayer, () orbitals in the relevant $t_{…

Finite energy spin fluctuation as a pairing glue in systems with coexisting electron and hole bands
Masahiro Nakata, Daisuke Ogura, Hidetomo Usui +1
We study, within the fluctuation exchange approximation, the spin-fluctuation-mediated superconductivity in Hubbard-type models possessing electron and hole bands, and compare them…
