Emergent cometlike swarming of optically driven thermally active colloids

Physical Review Letters 112:6 (2014)

Authors:

JA Cohen, R Golestanian

Abstract:

We propose a simple system of optically driven colloids that convert light into heat and move in response to self-generated and collectively generated thermal gradients. We show that the system exhibits self-organization into a moving cometlike swarm and characterize the structure and response of the swarm to a light-intensity-dependent external tuning parameter. We observe many interesting features in this nonequilibrium system including circulation and evaporation, intensity-dependent shape, density and temperature fluctuations, and ejection of hot colloids from the swarm tip. © 2014 American Physical Society.
