Query: Coexistence of nonequilibrium phases in assemblies of driven nematic
  colloids   We combine experiments, theory, and simulations to investigate the
coexistence of nonequilibrium phases emerging from interacting colloidal
particles that are electrokinetically propelled in a nematic liquid crystal
solvent. We directly determine the mechanical pressure within the radial
assemblies and measure a non-equilibrium equation of state for this athermal
driven system. A generic model combines phoretic propulsion with the interplay
between electrostatic effects and liquid-crystal-mediated hydrodynamics, which
are effectively cast into a long-range interparticle repulsion, while
elasticity plays a subdominant role. Simulations based on this model explain
the observed collective organization process and phase coexistence
quantitatively. Our colloidal assemblies provide an experimental test-bed to
investigate the fundamental role of phoretic pressure in the organization of
driven out-of-equilibrium matter.
