| Outline of Final Research Achievements |
We have been developing the first principles simulation methods and novel experimental methods for the hydrogen isotope nuclei (positive muon and proton) states in the materials, and investigating their behaviors and their induced new properties of materials. (1) We made the first principles simulation code “Naniwa”, for the positive muon, proton and other small mass nuclei in the material environments, and applied it to real material systems. (2) We also developed a new algorithm for electron-electron correlation energy calculations for the next generation first principles simulation methods. (3) We explored the new physical properties of metallic hydrides under high pressure by the first principles simulation. (4) We investigated the hydrogen states on solid surfaces and in their subsurfaces, and revealed the mechanisms of the catalytic reaction, diffusion, and desorption dynamics of hydrogen on metal surfaces with a combination of our developed experimental and simulation methods.
