题目:Crystal structure prediction method MAGUS and its application

报告人:孙建 教授(南京大学)

地点:紫金港校区东4-242

时间:2023320日(周一)下午15:30 

摘要:In this talk, I will introduce the machine learning and graph theory assisted crystal structure prediction method (MAGUS) [1] developed in my group. In addition, I will show some of our recent progress in the applications of this method to predict new compounds, including planetary minerals [2-6] and functional materials, including superhard, high energy density, and superconducting materials [7-8], etc.
