Role of Vertex Correction and Dimensionality on Superconductivity Induced by On-site Coulomb Repuls ion
Hirono Fukazawa, Hiroaki Ikeda, Kosaku Yamada
We evaluate the dominant superconducting pairing symmetry in some 3-dimensional cubic lattice struct ures within the third-order perturbation theory with respect to the on-site cou…

Perturbation Theory on the Superconductivity of Heavy Fermion Superconductors CeIr_{x}Co_{1-x}In_5
Yunori Nisikawa, Hiroaki Ikeda, Kosaku Yamada
We reformulate the Eliashberg's equation for the superconducting transition within the quasi-particle description, which takes account of the heavy electron mass. We discuss the su…
