Fourth Order Perturbation Theory for Normal Selfenergy in Repulsive Hubbard Model
Shogo Shinkai, Hiroaki Ikeda, Kosaku Yamada
We investigate the normal selfenergy and the mass enhancement factor in the Hubbard model on the two-dimensional square lattice. Our purpose in this paper is to evaluate the mass e…

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…
