Persistence is key—topological data analysis reveals hidden medium-range order in glass

By Lisa McDonald / September 11, 2020

Understanding the atomic structure of glass and other amorphous materials is difficult because, unlike crystals, the structure only consists of short-range and medium-range order; long-range order is absent. Researchers led by Aalborg University demonstrate how a topological method called persistent homology could help reveal a glass’s medium-range order structural features.
