Analysis of Superconductivity in d-p Model on Basis of Perturbation Theory
Sotaro Sasaki, Hiroaki Ikeda, Kosaku Yamada
We investigate the mass enhancement factor and the superconducting transition temperature in the d-p model for the high-$\Tc$ cuprates. We solve the Éliashberg equation using the t…

Perturbation Analysis of Superconductivity in the Trellis-Lattice Hubbard Model
Sotaro Sasaki, Hiroaki Ikeda, Kosaku Yamada
We investigate pairing symmetry and transition temperature in the trellis-lattice Hubbard model. We solve the Éliashberg equation using the third-order perturbation theory with res…

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…
