Elementary mechanisms governing the dynamics of silica

A full understanding of glasses requires an accurate atomistic picture of the complex activated processes that constitute the low-temperature dynamics of these materials. To this end, we generate over five thousand activated events in a model silica glass, using the activation–relaxation technique; these atomistic mechanisms are analyzed and...
