| Research Abstract |
By means of atomistic simulations, we have revealed some unknown behaviors of water (hydrogen) under high pressure such as new high-pressure phase of hydrous minerals, hydrogen-bonding of water molecules under high pressure and high temperature, proton conduction in high-pressure phase of ice, pressure-induced phase transition of hydrogen hydrate, high temperature superconductivity of hydrides under high pressure, failure simulation of nanopolycrystalline diamond.
