Structure and Dynamics of amorphous Silica Surfaces
Alexandra Roder, Walter Kob, Kurt Binder
We use molecular dynamics computer simulations to study the equilibrium properties of the surface of amorphous silica. Two types of geometries are investigated: i) clusters with di…
Finite-size scaling at the dynamical transition of the mean-field 10-state Potts glass
Claudio Brangian, Walter Kob, Kurt Binder
We use Monte Carlo simulations to study the static and dynamical properties of a Potts glass with infinite range Gaussian distributed exchange interactions for a broad range of tem…
Frequency dependent specific heat of viscous silica
Peter Scheidler, Walter Kob, Arnulf Latz +2
We apply the Mori-Zwanzig projection operator formalism to obtain an expression for the frequency dependent specific heat c(z) of a liquid. By using an exact transformation formula…
The entrance dynamics of polymers into a gel
Walter Kob, Leticia F. Cugliandolo
We use computer simulations to study the (driven) dynamics of a charged polymer in a disordered medium, thus mimicking the setting used in gel electrophoresis. In agreement with ex…
Equilibrating Glassy Systems with Parallel Tempering
Walter Kob, Claudio Brangian, Torsten Stuhn +1
We discuss the efficiency of the so-called parallel tempering method to equilibrate glassy systems also at low temperatures. The main focus is on two structural glass models, SiO_2…
The relaxation dynamics of a simple glass former confined in a pore
Peter Scheidler, Walter Kob, Kurt Binder
We use molecular dynamics computer simulations to investigate the relaxation dynamics of a binary Lennard-Jones liquid confined in a narrow pore. We find that the average dynamics…
