Query: Hydrodynamic Swarming of Thermally Active Dimeric Colloids   Self-propelled phoretic colloids have recently emerged as a promising avenue
for the design of artificial swimmers. These swimmers combine purely phoretic
interactions with intricate hydrodynamics which critically depend on the
swimmer shape. Thermophobic dimer shaped colloids are here investigated by
means of hydrodynamic simulations, from the single particle motion to their
collective behavior. The combination of phoretic repulsion with hydrodynamic
lateral attraction favors the formation of planar moving clusters. The
resulting hydrodynamic assembly in flattened swarms is therefore very specific
to these dimeric active colloids.
