Topogivity: A Machine-Learned Chemical Rule for Discovering Topological Materials
A fundamental question in the field of topological materials is why some materials are
topological while others are not. In this talk, I will discuss our work on a machine-learned
heuristic rule that diagnoses whether a material is topological using only its chemical formula.
Our approach enables chemical insights into electronic band topology via a notion that we term
topogivity, which is a numerical value for each chemical element that loosely captures its
tendency to form topological materials. By implementing a high-throughput procedure based on
heuristic rule prediction followed by ab initio validation, we discover new topological materials
that would have been difficult to find using existing methods.
