Abstract

Warm dense hydrogen is investigated by the ab initio molecular dynamics method near the fluid–fluid phase transition. The metastable states are calculated along isotherms of 700 and 1000 K. The obtained pressure ranges of metastable states are 0.47 and 0.32 Mbar, respectively. Their existence indicates that this transition is a first-order phase transition.
