Phase Behavior, Synchronization, and Emergent Flows of Spinning Magnetic Colloids

ORAL

Abstract

We study the collective motion, phase behavior, and synchronization of colloidal particles spun by a rotating magnetic field. We tune the inter-particle interactions, spinning speed, and particle shape, while imaging the orientation of each particle over time. I will discuss the observed phase transitions in structure and synchronicity, as well as the collective dynamics of the system.
