Aging Dynamics of a Fractal Model Gel
M-A. Suarez, N. Kern, E. Pitard +1
Using molecular dynamics computer simulations we investigate the aging dynamics of a gel. We start from a fractal structure generated by the DLCA-DEF algorithm, onto which we then…
Glass transitions in 1, 2, 3, and 4 dimensional binary Lennard-Jones systems
Ralf Brüning, Denis A. St-Onge, Steve Patterson +1
We investigate the calorimetric liquid-glass transition by performing simulations of a binary Lennard-Jones mixture in one through four dimensions. Starting at a high temperature,…
Static and dynamic properties of a reversible gel
Pablo I. Hurtado, Pinaki Chaudhuri, Ludovic Berthier +1
We study a microscopically realistic model of a physical gel and use computer simulations to investigate its static and dynamic properties at thermal equilibrium. The phase diagram…
On the relaxation dynamics of glass-forming systems: Insights from computer simulations
Pinaki Chaudhuri, Ludovic Berthier, Srikanth Sastry +1
We discuss the relaxation dynamics of a simple lattice gas model for glass-forming systems and show that with increasing density of particles this dynamics slows down very quickly.…
A genetic algorithm for the atomistic design and global optimisation of substitutionally disordered materials
Chris E. Mohn, Walter Kob
We present a genetic algorithm for the atomistic design and global optimisation of substitutionally disordered bulk materials and surfaces. Premature convergence which hamper conve…
Coupling/decoupling between translational and rotational dynamics in a supercooled molecular liquid
Song-Ho Chong, Walter Kob
We use molecular dynamics computer simulations to investigate the coupling/decoupling between translational and rotational dynamics in a glass-forming liquid of dumbbells. This is…
