Project:  First principles studies of ultra-hard materials under extremely high temperatures and pressures
Abstract:  Diamond is the known hardest material on earth. Although diamond is widely used in many areas of industry applications and has been studied for decades, how its strength changes under extremely high pressure and high temperature is theoret- ically unknown. For the first time, our group will apply a newly developed ab initio molecular dynamics method (AIMD) to calculate the ideal strength of diamond under various pressure and temperature conditions. With this project, we can provide a quantitative understanding of the strength of diamond under extreme conditions, which will be valuable for both industry and academic research.
