Liquid-glass transition in equilibrium

Probing a liquid to glass transition in equilibrium.

We use computer simulations to investigate the static properties of a simple glass-forming fluid in which the positions of a finite fraction of the particles have been frozen. By probing the equilibrium statistics of the overlap between independent configurations of the liquid, we find strong evidence that this random pinning induces a glass transition. At low temperatures, our numerical findin...

Liquid-Liquid Phase Transition and Glass Transition in a Monoatomic Model System

We review our recent study on the polyamorphism of the liquid and glass states in a monatomic system, a two-scale spherical-symmetric Jagla model with both attractive and repulsive interactions. This potential with a parametrization for which crystallization can be avoided and both the glass transition and the liquid-liquid phase transition are clearly separated, displays water-like anomalies a...

Interplay of the Glass Transition and the Liquid-Liquid Phase Transition in Water

Water has multiple glassy states, often called amorphous ices. Low-density (LDA) and high-density (HDA) amorphous ice are separated by a dramatic, first-order like phase transition. It has been argued that the LDA-HDA transformation connects to a first-order liquid-liquid phase transition (LLPT) above the glass transition temperature T(g). Direct experimental evidence of the LLPT is challenging...

The liquid-glass transition in sugars and sugar mixtures

The glass transition in sugars is important for several reasons. First, sugar glasses are very effective materials for cryopreservation and anhydrobiosis. Second, biochemists commonly use sugars to suspend biomaterials in a glassy matrix for spectroscopic studies. Third, the glass transition in sugars is important in the food industry. The texture of candies or cookies mainly depends on the gla...
