## Description

- description: 本論文では, TurboRVBを利用して得られた高圧水素のエネルギー計算から, 木星及び土星の惑星内部構造の研究に活用可能な「高圧水素の状態方程式」を構築した結果を報告する.
    これまで使われていたREOSと呼ばれる状態方程式は, 従前法であるDFT(PBE汎関数)を利用して得られたものであった. しかしながら,よく知られているように,
    DFTは高圧のような極限状況ではその予見の信頼性が担保されない. 第一原理量子モンテカルロ法(QMC)は, そのような予見不定性を解消する方法論であり, 今回得られた高圧水素の状態方程式は,
    惑星科学研究において利用される最も信頼性の高い状態方程式になることが期待される.
