Journal ArticleDOI
Testing mode-coupling theory for a supercooled binary Lennard-Jones mixture I: The van Hove correlation function.
Walter Kob,Hans C. Andersen +1 more
TL;DR: From the investigation of these correlation functions, it is concluded that hopping processes are not important on the time scale of the $\beta$-relaxation for this system and for the temperature range investigated.
Journal ArticleDOI
Dynamical heterogeneities in a supercooled lennard-jones liquid
TL;DR: In this article, the self part of the van Hove correlation function was used to identify mobile particles in supercooled Lennard-Jones liquid, and these particles formed clusters whose sizes grow with decreasing temperature.
Journal ArticleDOI
Stringlike cooperative motion in a supercooled liquid
Claudio Donati,Jack F. Douglas,Walter Kob,Steven J. Plimpton,Peter H. Poole,Sharon C. Glotzer +5 more
TL;DR: In this paper, extensive molecular dynamics simulations are performed on a glass-forming Lennard-Jones mixture to determine the nature of the cooperative motions occurring in this model fragile liquid, and they observe stringlike cooperative molecular motion (''strings'') at temperatures well above the glass transition.
Journal ArticleDOI
Cooling-rate effects in amorphous silica: A computer-simulation study.
TL;DR: Using molecular-dynamics computer simulations, it is demonstrated that the cooling-rate dependence of microscopic quantities is significantly more pronounced than the one of macroscopic properties, thus demonstrating that the used potential is a good model for silica glass.
Journal ArticleDOI
Scaling Behavior in the β -Relaxation Regime of a Supercooled Lennard-Jones Mixture
Walter Kob,Hans C. Andersen +1 more
TL;DR: The predictions of mode-coupling-theory on the existence of a von Schweidler law are found to hold for a molecular dynamics simulation of a supercooled binary Lennard-Jones mixture and the exponents in these two power-laws are very close to satisfying the exponent relationship predicted by the mode-Coupling theory.
