摘要: The melting of ice under pressure is investigated with a series first-principles molecular dynamics simulations. In particular, two-phase approach used to determine the temperature ice-VII phase in range 10–50 GPa. Our computed temperatures are consistent existing diamond anvil cell experiments. We find that for pressures between 10 and 40 GPa, melts as solid. For above ≈45 Gpa, there sharp increase slope curve because presence dissociation proton diffusion solid before melting. onset significant function increasing found be gradual bears many similarities type-II superionic
