Evidence for multiple liquid–liquid phase transitions in carbon, and the Friedel ordering of its liquid state
@article{Dharmawardana2022EvidenceFM, title={Evidence for multiple liquid–liquid phase transitions in carbon, and the Friedel ordering of its liquid state}, author={M. W. Chandre Dharma-wardana and Dennis D. Klug}, journal={Physics of Plasmas}, year={2022} }
Carbon, the fourth most abundant element in the Universe forms a metallic fluid with transient covalent bonds on melting. Its liquid-liquid phase transitions, intensely sought using simulations had been elusive. Here we use density functional theory (DFT) simulations with up to 108 atoms using molecular dynamics, as well as one-atom DFT as implemented in the neutral pseudo-atom method where multi-atom effects are treated by ion-ion correlation functionals. Both methods use electron-electron…

The results confirm predictions that the strength of the tetrahedral molecular orbital bonds in diamond persists under enormous pressure, resulting in large energy barriers that hinder conversion to more-stable high-pressure allotropes just as graphite formation from metastable diamond is kinetically hindered at atmospheric pressure.
