Depletion potentials in highly size-asymmetric binary hard-sphere mixtures: Comparison of accurate simulation results with theory
Douglas J. Ashton, Nigel B. Wilding, Roland Roth +1
We report a detailed study, using state-of-the-art simulation and theoretical methods, of the depletion potential between a pair of big hard spheres immersed in a reservoir of much…
Fluid phase coexistence and critical behaviour from simulations in the restricted Gibbs ensemble
Douglas J. Ashton, Nigel B. Wilding, Peter Sollich
The symmetrical restricted Gibbs ensemble (RGE) is a version of the Gibbs ensemble in which particles are exchanged between two boxes of fixed equal volumes. It has recently come t…
Relationship between vibrations and dynamical heterogeneity in a model glass former: extended soft modes but local relaxation
Douglas J. Ashton, Juan P. Garrahan
We study the relation between short-time vibrational modes and long-time relaxational dynamics in a kinetically constrained lattice gas with harmonic interactions between neighbour…
Fast Simulation of Facilitated Spin Models
Douglas J. Ashton, Lester O. Hedges, Juan P. Garrahan
We show how to apply the absorbing Markov chain Monte Carlo algorithm of Novotny to simulate kinetically constrained models of glasses. We consider in detail one-spin facilitated m…
