Transport properties of glass-formers near glass transition reflect the varying degrees of the sensitivity of the solid-like dynamics and structures with respect to temperature, depending on their fragility. Notably, however, most glasses resume Arrehenius transport behavior upon onset of...

An analysis of diffusion in a supercooled liquid based solely in the density of diffusive directions and the value of energy barriers shows how the potential energy landscape (PEL) approach is capable of explaining the α and β relaxations and the fragility of a glassy system. We find that the...

We treat liquid-to-glass transition as a sequence of self-similar “smeared” ideal transitions emerging at characteristic temperatures T0,Tg and Tc. The characteristic temperatures (Vogel–Fulcher T0, calorimetric Tg and crossover Tc temperatures) are discussed through the...
