Stochastic level-set method for shape optimisation
Lester O. Hedges, H. Alicia Kim, Robert L. Jack
We present a new method for stochastic shape optimisation of engineering structures. The method generalises an existing deterministic scheme, in which the structure is represented…
Crystallization and arrest mechanisms of model colloids
Thomas K. Haxton, Lester O. Hedges, Stephen Whitelam
We performed dynamic simulations of spheres with short-range attractive interactions for many values of interaction strength and range. Fast crystallization occurs in a localized r…
Growth of equilibrium structures built from a large number of distinct component types
Lester O. Hedges, Ranjan V. Mannige, Stephen Whitelam
We use simple analytic arguments and lattice-based computer simulations to study the growth of structures made from a large number of distinct component types. Components possess '…
Self-assembly at a nonequilibrium critical point
Stephen Whitelam, Lester O. Hedges, Jeremy D. Schmit
We use analytic theory and computer simulation to study patterns formed during the growth of two-component assemblies in 2D and 3D. We show that these patterns undergo a nonequilib…
Selective nucleation in porous media
Lester O. Hedges, Stephen Whitelam
Geometrical arguments suggest that pore-mediated nucleation happens in general in a two-step fashion, the first step being nucleation within the pore, the second being nucleation f…
Patterning a surface so as to speed nucleation from solution
Lester O. Hedges, Stephen Whitelam
Motivated by the question of how to pattern a surface in order to best speed nucleation from solution, we build on the work of Page and Sear [Phys. Rev. Lett. 97, 65701 (2006)] and…
