Graphic simulation of the electronic wave function (MLWF) in liquid carbon at a temperature of 9,000°Kelvin and five million atmospheres of pressure, showing a persistent covalent bonding even under these extreme conditions. At this pressure diamond melts at about 8,000°K.

A team based in Livermore has shed some light on the phase diagram of carbon at high pressure and temperature. In particular, the authors determined the solid/liquid and solid/solid phase boundaries for pressures up to 20 million atmospheres and more than 10,000 degrees Kelvin.
