Quantifying spatially heterogeneous dynamics in computer simulations of glass-forming liquids
نویسندگان
چکیده
We examine the phenomenon of dynamical heterogeneity in computer simulations of an equilibrium, glass-forming liquid. We describe several approaches for quantifying the spatial correlation of single-particle motion, and show that spatial correlations of particle displacements become increasingly long range as the temperature decreases toward the mode-coupling critical temperature.

Spatially Heterogeneous Dynamics in Liquids Near Their Glass Transition
Liquids near their glass transition are dynamically heterogeneous, and experiments and simulations have uncovered much about the rich and complex nature of this heterogeneity. This paper highlights key results from our computer simulation studies of spatially heterogeneous dynamics (SHD) in supercooled liquids near their glass transtion. We speculate on the relationship between SHD and other ph...
متن کاملMultiple time scales hidden in heterogeneous dynamics of glass-forming liquids.
A multitime probing of density fluctuations is introduced to investigate hidden time scales of heterogeneous dynamics in glass-forming liquids. Molecular-dynamics simulations for simple glass-forming liquids are performed and a three-time correlation function is numerically calculated for general time intervals. It is demonstrated that the three-time correlation function is sensitive to the het...
متن کاملDynamical Heterogeneity and Jamming in Glass-Forming Liquids†
The relationship between spatially heterogeneous dynamics (SHD) and jamming is studied in a glass-forming binary Lennard-Jones system via molecular dynamics simulations. It has been suggested [Phys. ReV. Lett. 2001, 86, 111]1 that the probability distribution of interparticle forces P(F) develops a peak at the glass transition temperature Tg and that the large force inhomogeneities, responsible...
متن کاملSpatially heterogeneous dynamics in supercooled liquids.
Although it has long been recognized that dynamics in supercooled liquids might be spatially heterogeneous, only in the past few years has clear evidence emerged to support this view. As a liquid is cooled far below its melting point, dynamics in some regions of the sample can be orders of magnitude faster than dynamics in other regions only a few nanometers away. In this review, the experiment...
متن کاملNon-monotonic temperature evolution of dynamic correlations in glass-forming liquids
The viscosity of glass-forming liquids increases by many orders of magnitude if their temperature is lowered by a mere factor of 2–3. Recent studies suggest that this widespread phenomenon is accompanied by spatially heterogeneous dynamics, and a growing dynamic correlation length quantifying the extent of correlated particle motion. Here we use a novel numerical method to detect and quantify s...
