We study experimentally and numerically the motion of a self-phoretic active particle in two-
dimensional loosely packed colloidal crystals at fluid interfaces. Two scenarios emerge …

We review recent experimental, numerical, and analytical results on active suspensions of
self-propelled colloidal beads moving in (quasi-) two dimensions. Active colloids form part of …

Using computer simulations we explore how grain boundaries can be removed from three-
dimensional colloidal crystals by doping with a small fraction of active colloids. We show that …

We present systematic numerical simulations to understand the behavior of colloidal
swimmers near a wall. We extend previous theoretical calculations based on lubrication …

Two-dimensional crystals on curved manifolds exhibit nontrivial defect structures. Here we
consider “active crystals” on a sphere, which are composed of self-propelled colloidal …

A recently introduced active phase field crystal model describes the formation of ordered
resting and traveling crystals in systems of self-propelled particles. Increasing the active …

Many types of active matter are deformable, such as epithelial cells and bacteria. To mimic
the feature of deformability, we built a model called an active colloidal cell (ACC), ie a …

Burgeoning experimental and simulation activity seeks to understand the existence of self-
assembled colloidal structures that are not close-packed,,,,,,,,. Here we describe an …

Active colloids self-organise into a variety of collective states, ranging from highly motile
“molecules” to complex 2D structures. Using large-scale simulations, we show that …

Active colloids constitute a novel class of materials composed of colloidal-scale particles
locally converting chemical energy into motility, mimicking micro-organisms. Evolving far …
