Universal nature of particle displacements close to glass and jamming transitions
Pinaki Chaudhuri, Ludovic Berthier, Walter Kob
We examine the structure of the distribution of single particle displacements (van-Hove function) in a broad class of materials close to glass and jamming transitions. In a wide ti…
Amorphous silica modeled with truncated and screened Coulomb interactions: A molecular dynamics simulation study
Antoine Carré, Ludovic Berthier, Juergen Horbach +2
We show that finite-range alternatives to the standard long-range BKS pair potential for silica might be used in molecular dynamics simulations. We study two such models that can b…
Revisiting the slow dynamics of a silica melt using Monte Carlo simulations
Ludovic Berthier
We implement a standard Monte Carlo algorithm to study the slow, equilibrium dynamics of a silica melt in a wide temperature regime, from 6100 K down to 2750 K. We find that the av…
Spatial correlations in the dynamics of glassforming liquids: Experimental determination of their temperature dependence
Cécile Dalle-Ferrier, Caroline Thibierge, Christiane Alba-Simionesco +6
We use recently introduced three-point dynamic susceptibilities to obtain an experimental determination of the temperature evolution of the number of molecules, N_corr, that are dy…
Structure and dynamics in glass-formers: predictability at large length scales
Ludovic Berthier, Robert L. Jack
Dynamic heterogeneity in glass-formers has been related to their static structure using the concept of dynamic propensity. We re-examine this relationship by analyzing dynamical fl…
The slow dynamics of glassy materials: Insights from computer simulations
Ludovic Berthier
The physics of glasses can be studied from many viewpoints, from material scientists interested in the development of new materials to statistical physicists inventing new theoreti…
Efficient measurement of linear susceptibilities in molecular simulations: Application to aging supercooled liquids
Ludovic Berthier
We propose a new method to measure time-dependent linear susceptibilities in molecular simulations, which does not require the use of nonequilibrium simulations, subtraction techni…
