Geodesic Trapping and Escape of Active Particles on Curved Surfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Active particles on curved surfaces can become trapped along closed geodesics even without physical barriers. We show that escape from these geometric traps exposes a fundamental d…

Collective dynamics of active suspensions on curved viscous interfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Self-propelled particles can navigate complex environments, including viscous fluid interfaces with curved geometries. In this work, we study the emergent dynamics of a suspension…
