Duality between random trap and barrier models
Robert L. Jack, Peter Sollich
We discuss the physical consequences of a duality between two models with quenched disorder, in which particles propagate in one dimension among random traps or across random barri…
A polydisperse lattice-gas model
Nigel B. Wilding, Peter Sollich, Matteo Buzzacchi
We describe a lattice-gas model suitable for studying the generic effects of polydispersity on liquid-vapor phase equilibria. Using Monte Carlo simulation methods tailored for the…
Weakly polydisperse systems: Perturbative phase diagrams that include the critical region
Peter Sollich
The phase behaviour of a weakly polydisperse system, such as a colloid with a small spread of particle sizes, can be related perturbatively to that of its monodisperse counterpart.…
Aging in One-Dimensional Coagulation-Diffusion Processes and the Fredrickson-Andersen Model
Peter Mayer, Peter Sollich
We analyse the aging dynamics of the one-dimensional Fredrickson-Andersen (FA) model in the nonequilibrium regime following a low temperature quench. Relaxation then effectively pr…
