Efficient Monte Carlo simulation of a glass forming binary mixture
Elijah Flenner, Grzegorz Szamel
We propose and use a novel, hybrid Monte Carlo algorithm that combines configurational bias particle swaps with parallel tempering. We use this new method to simulate a standard mo…
Nature of the Breakdown in the Stokes-Einstein Relationship in a Hard Sphere Fluid
Sanat K. Kumar, Grzegorz Szamel, Jack F. Douglas
Molecular Dynamics simulations of high density hard sphere fluids clearly show a breakdown of the Stokes-Einstein equation (SE). This result has been conjectured to be due to the p…
Time scale for the onset of Fickian diffusion in supercooled liquids
Grzegorz Szamel, Elijah Flenner
We propose a quantitative measure of a time scale on which Fickian diffusion sets in for supercooled liquids and use Brownian Dynamics computer simulations to determine the tempera…
Relaxation in a glassy binary mixture: Comparison of the mode-coupling theory to a Brownian dynamics simulation
Elijah Flenner, Grzegorz Szamel
We solved the mode-coupling equations for the Kob-Andersen binary mixture using the structure factors calculated from Brownian dynamics simulations of the same system. We found, as…
Relaxation in a glassy binary mixture: Mode-coupling-like power laws, dynamic heterogeneity and a new non-Gaussian parameter
Elijah Flenner, Grzegorz Szamel
We examine the relaxation of the Kob-Andersen Lennard-Jones binary mixture using Brownian dynamics computer simulations. We find that in accordance with mode-coupling theory the se…
