Aggregation of self-propelled colloidal rods near confining walls
Aggregation of self-propelled colloidal rods near confining walls
The nonequilibrium collective behavior of self-propelled colloidal rods in a confining channel is studied using Brownian dynamics simulations and dynamical density functional theory. We observe an aggregation process in which rods self-organize into transiently jammed clusters at the channel walls. In the early stage of the process, fast-growing hedgehoglike clusters …
