| Research Abstract |
We developed methods to calculate superconducting transition temperatures from first principles. As for the approach combining density functional theory and many-body methods, we formulated schemes taking account of the spin-orbit coupling and the electron-phonon coupling. For superconducting density functional theory, we developed a scheme for the plasmon mechanism. We applied these methods to iron-based superconductors, layered nitrides, heavy fermion systems, carbon-based superconductors, and elemental lithium under high pressures.
