Various static and dynamic phenomena displayed by glass-forming liquids, particularly those near the so-called "fragile" limit, emerge as manifestations of the multidimensional complex topography of the collective potential energy function. These include non-Arrhenius viscosity and relaxation times, bifurcation between the α- and β-relaxation processes, and a breakdown of the Stokes-Einstein relation for self-diffusion. This multidimensional viewpoint also produces an extension of the venerable… Expand
Salient properties of glassforming liquids close to the glass transition
Abstract This article is focused on the dramatic increase of the viscosity, or on the relaxation time of supercooled molecular liquids, and on the dynamical arrest observed when the temperature isExpand
Tracer diffusion in glassforming liquids
In the last decades, a wide collection of experimental evidence has been found in the study of supercooled glassformers on the existence of a crossover between two dynamical regimes at a temperatureExpand
Universal Nucleation Behaviour of Sheared Systems
Using molecular simulations and a modified Classical Nucleation Theory, we study the nucleation, under flow, of a variety of liquids: different water models, Lennard-Jones and hard sphere colloids.Expand
Understanding the viscosity of supercooled liquids and the glass transition through molecular simulations
Abstract We discuss a potential energy landscape (PEL) approach to calculate the characteristically sluggish viscous behaviour of supercooled liquids. This phenomenon is central to the theoreticalExpand
Universal Nucleation Behavior of Sheared Systems.
Using molecular simulations and a modified classical nucleation theory, a simplified version of the theory successfully captures the nonmonotonic temperature dependence of the nucleation behavior, which is shown to originate from the violation of the Stokes-Einstein relation. Expand
Glass transition in supercooled fluids of soft spheres
Abstract We locate the glass transition lines in the temperature–density plane for supercooled fluids of particles interacting with an inverse-power r − n potential in the cases n = 4 , 6 , 9 and 12,Expand
Properties of ideal Gaussian glass-forming systems.
The ideal Gaussian glass-forming system is introduced as a model to describe the thermodynamics and dynamics of supercooled liquids on a local scale in terms of the properties of the potential energy landscape (PEL) to identify a relevant PEL parameter determining the kinetic fragility. Expand
Nonequilibrium thermodynamics and glassy rheology
Mechanically driven glassy systems and complex fluids exhibit a wealth of rheological behaviors that call for theoretical understanding and predictive modeling. A distinct feature of theseExpand

It is found that, under cooling, the total structural relaxation becomes delayed as compared with the decay of the component of the intermediate scattering function corresponding to the main peak of the structure factor. Expand
Apparent correlations between the static length of relaxation and the linear size of dynamic heterogeneity in fragile liquids
Abstract.The most puzzling aspect of the glass transition observed in laboratory is the decoupling of the dynamics from the structure. As an attempt to reconcile the dynamic and the staticExpand

The objective of this paper is to relate a and ~ to gross topographical features of the many-particle potential-energy hypersurface and to conclude that a should decline with decreasing temperature. Expand
Supercooled liquids, glass transitions, and the Kauzmann paradox
Many liquids have heat capacities that substantially exceed those of the corresponding crystal, and this discrepancy magnifies in the supercooled regime. Thus, liquid entropy declines more rapidlyExpand
Nonexponential relaxations in strong and fragile glass formers
Deviations from thermally activated and from exponential response are typical features of the vitrification phenomenon and previously have been studied using viscoelastic, dielectric, calorimetric,Expand
Models of the glass transition
The different physical aspects of glass transitions are reviewed and models aiming at their explanation are described. The following three main aspects are distinguished: the degree of stability ofExpand

Any molecular system explores significantly different regions of the potential‐energy hypersurface as the system is found, respectively, in the solid and liquid phases. We study in detail theExpand

Owing to a suitable combination of domain parameters (mean size, lifetime, concentration, internal viscosity), the observed diffusion rate discrepancy can indeed be rationalized. Expand

The Microscopic Basis of the Glass Transition in Polymers from Neutron Scattering Studies
The connection between this boson peak and the fast dynamic process appearing near Tg is discussed, and the time-temperature superposition principle, which is valid for polymers on a macroscopic scale, is not applicable for temperatures approaching Tg. Expand
