Flowing Active Liquids in a Pipe: Hysteretic Response of Polar Flocks to External Fields
We investigate the response of colloidal flocks to external fields. We first show that individual colloidal rollers align with external flows, as would a classical spin with magnetic fields. Assembling polar active liquids from colloidal rollers, we experimentally demonstrate their hysteretic respon...
