a, Experimental reconstructions of the radial distribution function for complete melting at (160 ± 14) GPa and comparison with the simulation of the best fit to the corresponding XRD pattern and a simple Lennard–Jones liquid at 3.8 g cm−3 and 7,000 K. b, Our results for the fluid–solid coexistence and the pure fluid shown in context with the predictions of the carbon melting line and coordination numbers for liquid carbon. The temperature uncertainties shown arise from the error estimations of the DFT-MD fits, and the pressure uncertainties correspond to the values quoted in Fig. 2.
