Activated aging dynamics and negative fluctuation-dissipation ratios
Peter Mayer, Sébastien Léonard, Ludovic Berthier +2
In glassy materials aging proceeds at large times via thermal activation. We show that this can lead to negative dynamical response functions and novel and well-defined violations…
Caging and mosaic lengthscales in plaquette spin models of glasses
Robert L. Jack, Juan. P. Garrahan
We consider two systems of Ising spins with plaquette interactions. They are simple models of glasses which have dual representations as kinetically constrained systems. These mode…
Dynamical Exchanges in Facilitated Models of Supercooled liquids
YounJoon Jung, Juan P. Garrahan, David Chandler
We investigate statistics of dynamical exchange events in coarse--grained models of supercooled liquids in spatial dimensions , 2, and 3. The models, based upon the concept of…
Decoupling of self-diffusion and structural relaxation during a fragile-to-strong crossover in a kinetically constrained lattice gas
Albert C. Pan, Juan P. Garrahan, David Chandler
We present an interpolated kinetically constrained lattice gas model which exhibits a transition from fragile to strong supercooled liquid behavior. We find non-monotonic decouplin…
Numerical study of a fragile three-dimensional kinetically constrained model
Ludovic Berthier, Juan P. Garrahan
We numerically study the three-dimensional generalization of the kinetically constrained East model, the North-or-East-or-Front (NEF) model. We characterize the equilibrium behavio…
Glassy behaviour in an exactly solved spin system with a ferromagnetic transition
Robert L. Jack, Juan P. Garrahan, David Sherrington
We show that applying simple dynamical rules to Baxter's eight-vertex model leads to a system which resembles a glass-forming liquid. There are analogies with liquid, supercooled l…
