Preparation and relaxation of very stable glassy states of a simulated liquid
Robert L. Jack, Lester O. Hedges, Juan P. Garrahan +1
We prepare metastable glassy states in a model glass-former made of Lennard-Jones particles by sampling biased ensembles of trajectories with low dynamical activity. These trajecto…
Excitations are localized and relaxation is hierarchical in glass-forming liquids
Aaron S. Keys, Lester O. Hedges, Juan P. Garrahan +2
For several atomistic models of glass formers, at conditions below their glassy dynamics onset temperatures, , we use importance sampling of trajectory space to stu…
Limit of validity of Ostwald's rule of stages in a statistical mechanical model of crystallization
Lester O. Hedges, Stephen Whitelam
We have only rules of thumb with which to predict how a material will crystallize, chief among which is Ostwald's rule of stages. It states that the first phase to appear upon tran…
