Tech News 1: Machine-learning model shows diamond melting at high pressure
Posted: Thu Jan 27, 2022 3:44 am
A Sandia National Laboratories supercomputer simulation model called SNAP that rapidly predicts the behavior of billions of interacting atoms has captured the melting of diamond when compressed by extreme pressures and temperatures. At several million atmospheres, the rigid carbon lattice of the hardest known substance on Earth is shown in SNAP (Spectral Neighbor Analysis Potential) simulations to crack, melt into amorphous carbon and then recrystallize. The work could aid understanding of the internal...
