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…
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…
Fluctuation-dissipation relations in the non-equilibrium critical dynamics of Ising models
Peter Mayer, Ludovic Berthier, Juan P. Garrahan +1
We investigate the relation between two-time, multi-spin, correlation and response functions in the non-equilibrium critical dynamics of Ising models in d=1 and d=2 spatial dimensi…
Hiking through glassy phases: physics beyond aging
Ludovic Berthier, Virgile Viasnoff, Olivia White +2
Experiments performed on a wide range of glassy materials display many interesting phenomena, such as aging behavior. In recent years, a large body of experiments probed this noneq…
