This review shows the highlights of a 4-year-long research project supported by the
Japanese Government to explore new superconducting materials and relevant functional …

We review the recent progress in the density functional theory for superconductors (SCDFT).
Motivated by the long-studied plasmon mechanism of superconductivity, we have …

We extend the two leading methods for the ab initio computational description of phonon-
mediated superconductors, namely Eliashberg theory and density-functional theory for …

We extend the density-functional theory for superconductors (SCDFT) to take account of the
dynamical structure of the screened Coulomb interaction. We construct an exchange …

We revealed a detailed phase diagram of the very lightly doped regime in Li-intercalated
superconductors, Li x ZrNCl, to which previous studies have never gained access owing to …

A distinctive feature of layered conductors is the presence of low-energy electronic collective
modes of the conduction electrons. This affects the dynamic screening properties of the …

A novel collective excitation is predicted to exist at metal surfaces where a two-dimensional
surface state band coexists with the underlying three-dimensional continuum. This is a low …

NaAlSi is an sp electron superconductor crystallizing in a layered structure of the anti-PbFCl
type with a relatively high transition temperature T c of~ 7 K. Recent electronic state …

Recently, a low-energy collective excitation has been predicted to exist at metal surfaces
where a quasi two-dimensional (2D) surface-state band coexists with the underlying three …

We present an ab initio analysis with density functional theory for superconductors (SCDFT)
to understand the superconducting mechanism of doped layered nitrides β-Li x M NCl (M …
