Spontaneous Demixing of Binary Colloidal Flocks
Samadarshi Maity, Alexandre Morin
Population heterogeneity is ubiquitous among active living systems, but little is known about its role in determining their spatial organization and large-scale dynamics. Combining…

Flowing active liquids in a pipe: Hysteretic response of polar flocks to external fields
Alexandre Morin, Denis Bartolo
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 magneti…
