Universal emergent dynamics of micro-spinners above a wall

ORAL

Abstract

We study the collective behavior in ensembles of micro-spheres driven to rotate above a wall. This many particle system is Hamiltonian and the ensemble rotates about its center of mass. Using large-scale computations that resolve the interactions with the wall, hydrodynamics and particle collisions, we study the emergence of collective rotation, edge currents and universal behaviors that depend on the density and height.
