| Outline of Final Research Achievements |
By employing the Green's-function method and diffusion Monte Carlo simulations, we have studied quantum many-body problems in condensed matter physics, based primarily on the first-principles Hamiltonian from a perspective of pursuing new concepts, new phenomena, and new methodologies in the density functional theory rather than investigating materials properties. Special attention is paid to the system of a single proton embedded in the electron gas to reveal that a Kondo spin-singlet resonance state emerges in the intermediate densities with the Kondo temperature well beyond 1,000K, indicating that a room temperature superconductor might be obtained, if protons are introduced into a metal with an appropriate density in a regular array to form a Kondo lattice system. We also find a possibility of the universal transition into a phase with a very small effective mass at very low densities.
