Understanding the microscopic mechanism of the transition of glass remains one of the most challenging topics in Condensed Matter Physics. What controls the sharp slowing down of …
We provide a theoretical description of dynamical heterogeneities in glass-forming liquids, based on the premise that relaxation occurs via local rearrangements coupled by elasticity …
The present work studies the mechanisms controlling the energy barrier for ion hopping in conducting polymers. Polymer electrolytes usually show Arrhenius-like temperature …
The conventional understanding of the glass transition is that the transition from glass to liquid appears as a dynamic process in which atoms or molecules relax cooperatively into …

The variation of polymer topology provides an alternative way to tune the properties of polymer materials without varying the chemistry of the monomers composing the polymer …
Numerous experimental and computational studies have established that most liquids seem to exhibit a remarkable, yet poorly understood, property termed “thermodynamic scaling”, in …
Several theories of the glass transition propose that the structural relaxation time τ α is controlled by a growing static length scale ξ that is determined by the free energy landscape …
The emergence of the solid state in glass-forming materials upon cooling is accompanied by changes in both thermodynamic and viscoelastic properties and by a precipitous drop in …

This article gives an overview of experimental results on dynamics in bulk glass-forming molecular liquids. Rather than looking for phenomenology that is universal, in the sense that …
