Journal ArticleDOI
Phase behaviour of metastable water
TL;DR: In this article, the authors present a comprehensive series of molecular dynamics simulations which suggest that the supercooling anomalies are caused by a newly identified critical point above which the two metastable amorphous phases of ice (previously shown to be separated by a line of first-order transitions) become indistinguishable.
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
Relation between the Widom line and the dynamic crossover in systems with a liquid–liquid phase transition
Limei Xu,Pradeep Kumar,Sergey V. Buldyrev,Shawhorng Chen,Peter H. Poole,Francesco Sciortino,H. E. Stanley +6 more
TL;DR: It is argued that this connection between C(P)(max) and dynamic crossover is not limited to the case of water, a hydrogen bond network-forming liquid, but is a more general feature of crossing the Widom line.
Journal ArticleDOI
Spatial correlations of mobility and immobility in a glass-forming Lennard-Jones liquid
TL;DR: Using extensive molecular dynamics simulations of an equilibrium, glass-forming Lennard-Jones mixture, it is shown that spatial correlations exist among particles undergoing extremely large ("mobile") or extremely small ("immobile") displacements over a suitably chosen time interval.
