On the temperature dependence of cooperative relaxation properties in glass-forming liquids. The nature of the glassy state and the behavior of liquids at low temperatures. Viscous liquids and the glass transition: A potential energy barrier picture. A topographic view of supercooled liquids and glass formation. Signatures of distinct dynamical regimes in the energy landscape of a glass-forming liquid. Our results indicate that the thermodynamic approach might be extended to predict the dynamical behaviour of supercooled liquids in general. We find that the thermodynamic approach can be used to understand the characteristic dynamic anomalies, and that the diffusive dynamics are governed by the configurational entropy. We calculate the configurational entropy at points spanning a large region of the temperature–density plane, using a model 11 that reproduces the dynamical anomalies of liquid water. Here we report a stringent test of the thermodynamic approach for liquid water (a convenient system to study because of an anomalous pressure dependence in the diffusion constant). The ‘thermodynamic approach’ to the glass transition considers the reduction in configuration space 4, 5, 6, 7, 8 explored as the system cools, and predicts that the configurational entropy 5, 9, 10 (a measure of the number of local potential energy minima sampled by the liquid) is related to the diffusion constant. As a result, the liquid dynamics at low temperature are related to the system's exploration of its own configuration space. The liquid experiences localized vibrations in the basins of attraction surrounding the minima, and rearranges via relatively infrequent inter-basin jumps 3. As a liquid approaches the glass transition, its properties are dominated by local potential minima 1, 2 in its energy landscape.
