Active matter is an exciting area of study that displays promising new
behaviors previously unobtainable in equilibrium systems and could
help bridge the gap between equilibrium colloidal- and nanoscale-
particles and living cells. In this talk, we present new results of
novel behaviors that can be observed in confined "cells" of
rotationally-driven particles with and without active boundaries. We
observe different classes of compartmentalization, which are
controllable and can be switched over time. Our results are obtained
using microscopic, non-momentum-conserving Langevin dynamics
simulations and confirmed via a phase field continuum model coupled to
a Navier-Stokes equation that we derive to incorporate hydrodynamic
effects. Our findings provide motivation and design rules for the
fabrication of primitive colloidal machines.
