Network formation and relaxation dynamics in a new model for colloidal gelation
E. Del Gado, W. Kob
We investigate the gel formation from the equilibrium sol phase in a simple model that has the characteristics of (colloidal) gel-forming systems at a finite temperature. At low vo…
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…
Structure and dynamics of l-Ge: Neutron scattering experiments and ab initio molecular dynamics simulations
Virginie Hugouvieux, Emmanuel Farhi, Mark R. Johnson +3
We report the first measurements of the dynamics of liquid germanium (l-Ge) by quasi-elastic neutron scattering on time-of-flight and triple-axis spectrometers. These results are c…
