Perspective: The glass transition.
We provide here a brief perspective on the glass transition field. It is an assessment, written from the point of view of theory, of where the field is and where it seems to be heading. We first give an overview of the main phenomenological characteristics, or "stylised facts," of the glass transition problem, i.e., the central observations that a theory of the physics of glass formation should...
متن کاملThe laboratory glass transition.
The phenomenology of the laboratory glass transition is examined in the enthalpy landscape framework. It is shown that a generic description of the glassy state based on partitioning of the phase space caused by the finiteness of the time of observation explains all universal features of glass transition. Using this description of glass, which is referred to as the extrinsically constrained liq...
متن کاملThe protein-solvent glass transition.
The protein dynamical transition and its connection with the liquid-glass transition (GT) of hydration water and aqueous solvents are reviewed. The protein solvation shell exhibits a regular glass transition, characterized by steps in the specific heat and the thermal expansion coefficient at the calorimetric glass temperature T(G) approximately 170 K. It implies that the time scale of the stru...
متن کاملWater's second glass transition.
The glassy states of water are of common interest as the majority of H2O in space is in the glassy state and especially because a proper description of this phenomenon is considered to be the key to our understanding why liquid water shows exceptional properties, different from all other liquids. The occurrence of water's calorimetric glass transition of low-density amorphous ice at 136 K has b...
متن کاملTheories of glass formation and the glass transition.
This key-issues review is a plea for a new focus on simpler and more realistic models of glass-forming fluids. It seems to me that we have too often been led astray by sophisticated mathematical models that beautifully capture some of the most intriguing features of glassy behavior, but are too unrealistic to provide bases for predictive theories. As illustrations of what I mean, the first part...
