We calculated a four-point correlation function G4(k, r; t) and the corresponding structure factor S 4 (K, ; t) for a model glass-forming binary mixture. These functions measure the spatial correlations of the relaxation of different particles. We found that these four-point functions are anisotropic and depend on the angle between vectors k and r (or q). The anisotropy is the strongest for times somewhat longer than the β relaxation time, but it is quite pronounced even for times comparable to… Expand
Multi-time density correlation functions in glass-forming liquids: Probing dynamical heterogeneity and its lifetime.
TLDR
The results show that the lifetime of the dynamical heterogeneity becomes much slower than the alpha-relaxation time that is determined from the two-point density correlation function when the system is highly supercooled. Expand
Large and Long-Range Dynamic Correlations in Supercooled Fluids Revealed via Four-Point Correlation Functions.
TLDR
It is shown that a four-point structure factor slightly different from the one commonly used reveals the existence of large and long-range dynamic correlations, which dominate the correlations identified with dynamic heterogeneity. Expand
Short-?and long-range correlated motion observed in colloidal glasses and liquids
We use a confocal microscope to examine the motion of individual particles in a dense colloidal suspension. Close to the glass transition, particle motion is strongly spatially correlated. TheExpand

Lifetimes and lengthscales of structural motifs in a model glassformer.
TLDR
A strong, but indirect, correlation between static structural ordering and slow dynamics is found in a popular model glassformer, the Kob-Andersen binary Lennard-Jones mixture. Expand
Distributions of pore sizes and atomic densities in binary mixtures revealed by molecular dynamics simulations.
TLDR
To quantify the pore-size distributions, a scaling relation is put forth that provides a satisfactory data collapse in systems with high porosity, and it is found that the local density of the solid domains in the porous structures is broadly distributed, and, with increasing average density, a distinct peak in the localdensity distribution is displaced toward higher values. Expand
Spatiotemporal intermittency and localized dynamic fluctuations upon approaching the glass transition.
TLDR
It is shown that the spatial heterogeneity of the dynamics extends to large length scales containing tens to hundreds of particles, corresponding to the timescale of maximally non-Gaussian dynamics. Expand

Anisotropic cooperative structural rearrangements in sheared supercooled liquids.
TLDR
In the non-Newtonian regime, where marked shear-thinning behavior appears, a novel dynamic effect is found: the mobile region tends to form anisotropic "fluidized bands," which suggests a link between nonlinear rheology and inhomogeneization of flow. Expand
Size dependence of dynamic fluctuations in liquid and supercooled water.
TLDR
Analyzing a 250 000 molecules simulated system, it is shown that both the magnitude of the departure from the value expected for the system-size dependence of an uncorrelated system and the system size at which such a trivial regime is finally recovered clearly increase upon supercooling, providing an upper limit to the maximum length scale of influence of the regions of correlated mobile molecules.

TLDR
A simple way of quantification in terms of the strength and the length scale of dynamic correlations among different particles is demonstrated, and it is shown that for appropriately chosen X(i)(t) the authors obtain finite cooperativity in the limit t-->infinity. Expand

TLDR
The wave-vector-dependent relaxation time is shown to be qualitatively different from the predictions of the mode-coupling theory for temperatures where hopping-like motion is present, and there are substantial differences for the non-Gaussian parameter. Expand

TLDR
The four-point correlation function that characterizes nontrivial cooperative dynamics in glassy systems within several models of glasses is computed, finding that the exponent mu is rather small, mu<1 , with a value in reasonable agreement with the MCT predictions, but not with the prediction of simple diffusive defect models, KCM's with noncooperative defects, and CRR's.

TLDR
A new non-Gaussian parameter is defined whose maximum occurs approximately at the time at which the two peaks in the probability distribution of the logarithm of displacements are most evident, approaching the commonly reported mode-coupling temperature. Expand
