Category: Academic

Description:

Populations of self-propelled living or synthetic microparticles, e.g., bacteria or chemically-activated colloids can collectively exhibit behavior that on the macroscale resembles fluid flow. While the individual particles are governed by relatively simple dynamics, the interaction of the particles can result in remarkably complex and intriguing phenomena. We study the collective behavior of self-rotating colloids suspended in viscous fluid. I will present experiments in our Lab with Quincke rotors (actuated by electric fields) which show the emergence of structure (e.g. vortices, crystals, chains) and discuss our discrete-particle and continuum models of these systems.
