Coarse-grained depletion potentials for anisotropic colloids: application to lock-and-key systems
Clement Law, Douglas J. Ashton, Nigel B. Wilding +1
When a colloid is mixed with a depletant such as a non-adsorbing polymer, one observes attractive effective interactions between the colloidal particles. If these particles are ani…
Unusual liquid phases for indented colloids with depletion interactions
Douglas J. Ashton, Robert L. Jack, Nigel B. Wilding
We study indented spherical colloids, interacting via depletion forces. These systems exhibit liquid-vapor phase transitions whose properties are determined by a combination of str…
Self-assembly and crystallisation of indented colloids at a planar wall
Douglas J. Ashton, Samantha J. Ivell, Roel P. A. Dullens +3
We report experimental and simulation studies of the structure of a monolayer of indented ("lock and key") colloids, on a planar surface. On adding a non-absorbing polymer with pre…
Three-body interactions in complex fluids: virial coefficients from simulation finite-size effects
Douglas J. Ashton, Nigel B. Wilding
A simulation technique is described for quantifying the contribution of three-body interactions to the thermodynamical properties of coarse-grained representations of complex fluid…
Quantifying the effects of neglecting many-body interactions in coarse-grained models of complex fluids
Douglas J. Ashton, Nigel B. Wilding
We describe a general simulation scheme for assessing the thermodynamic consequences of neglecting many-body effects in coarse-grained models of complex fluids. The method exploits…
Monte Carlo methods for estimating depletion potentials in highly size-asymmetrical hard sphere mixtures
D. J. Ashton, V. Sanchez-Gil, N. B. Wilding
We investigate Monte Carlo simulation strategies for determining the effective ("depletion") potential between a pair of hard spheres immersed in a dense sea of much smaller hard s…
