Title: Liquid–liquid phase transition in hydrogen by coupled electron–ion Monte Carlo simulations

Journal Article · · Proceedings of the National Academy of Sciences of the United States of America

We report results of quantum Monte Carlo simulations that indicate that the two phenomena occur simultaneously through a first-order phase transition in fluid hydrogen at megabar pressures and temperatures of 1,000 K. The predicted pressures are close to claims of metallization based on static compression experiments but are lower than that of recent dynamic compression measurements. The simulation results represent the most reliable theoretical prediction yet of the liquid–liquid transition in hydrogen and provide constraints for future experiments.
