We heat our samples substantially above the melting line and observe a plateau in a temperature vs. laser power curve that otherwise increases with power. This anomaly in the heating curve appears correlated with theoretical predictions for the plasma phase transition.en-USEvidence of a Liquid-Liquid Phase Transition in Hot Dense HydrogenJournal Article2014-09-1610.1073/pnas.1300718110
