核量子性を取り入れた量子分子動力学法の構築と水素分子量子凝縮体への分子科学的アプローチ

Abstract

We have developed a quantum molecular dynamics simulation method which can widely search hydrogen systems from an isolated hydrogen molecule to condensed phase hydrogens exhibiting strong nuclear quantum effects such as zero-point energy and nuclear delocalization. We will briefly summarize derivations and advantages of our method and report our recent results on liquid, solid and supercooled hydrogens, suggesting new molecular pictures and guiding insights useful for future experiments of these mysterious quantum molecules.
