Unifying dynamics of glass-forming liquids by crystallization temperature

A crucial question pertaining to the understanding of the elusive glass transition concerns the existence of a universal framework that can describe the dynamics of various glass-forming liquids. Here, we report our achievement of a comprehensive unification of dynamics via the utilization of the crystallization temperature. We provide evidence that the pressure-dependent crystallization temperature links numerous pivotal features of multiple glass-forming liquids, including the super-Arrhenius structural relaxation, dynamical heterogeneity, caging behavior, glass fragility, onset temperature and glass transition temperature. The significant role played by the crystallization temperature reveals the underlying connections between non-equilibrium glass formers and their equilibrium counterparts.
