Sommaire:

Many materials that form polycrystalline solids can also form glasses, e.g. metallic glasses. In this talk, I will primarily discuss the physics behind the competitions between crystallization and vitrification. I will introduce a new model, termed as the Arrow-Potts model, that combines the physics behind glassy dynamics with crystallization kinetics and arrive at a new analytical formula to understand and predict the time scales of crystallization. The analytical formula is obtained by deriving a unified theory that combines the field theory of nucleation with the dynamical facilitation theory of glasses, and Kolmogorov's statistical theory of crystal coarsening.
