Dynamical heterogeneity in a glass-forming ideal gas

Dynamical 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...

Dynamical heterogeneity in a vapor-deposited polymer glass.

Recently, there has been great interest in "ultrastable" glasses formed via vapor deposition, both because of emerging engineering applications of these materials (e.g., active layers in light-emitting diodes and photovoltaics) and, theoretically, as materials for probing the equilibrium properties of glassy materials below their glass transition, based on the conjecture that these materials ar...

Time asymmetry in a dynamical model of the one-dimensional ideal gas

We present a simple dynamical model of the one-dimensional ideal gas and show how it can be used to introduce a number of fundamental ideas in statistical mechanics. We use the model to illustrate the role of initial conditions in explaining time asymmetry and show that although the dynamical model is time-reversal invariant, the macroscopic behavior of the gas can be time-asymmetric if the ini...
