Perturbation Theory for a Repulsive Hubbard Model in Quasi-One-Dimensional Superconductors
Sotaro Sasaki, Hiroaki Ikeda, Kosaku Yamada
We investigate pairing symmetry and a transition temperature in a quasi-one-dimensional repulsive Hubbard model. We solve the Eliashberg equation using the third-order perturbation…

Possibility of f-wave spin-triplet superconductivity in the CoO superconductor: a case study on a 2D triangular lattice in the repulsive Hubbard model
Hiroaki Ikeda, Yunori Nisikawa, Kosaku Yamada
Stimulated by the recent finding of NaCoO.1.3HO superconductor, we investigate superconducting instabilities on a 2D triangular lattice in the repulsive Hubbard mo…
