Shape transitions of sedimenting confined droplets and capsules: from oblate to bullet-like geometries
Danilo P. F. Silva, Rodrigo C. V. Coelho, Ariel Dvir +4
The transport and deformation of confined droplets and flexible capsules are central to diverse phenomena and applications, from biological flows in microcapillaries to industrial…
A geometric condition for robot-swarm cohesion and cluster-flock transition
Mathias Casiulis, Eden Arbel, Charlotte van Waes +4
We present a geometric design rule for size-controlled clustering of self-propelled particles. We show that active particles that tend to rotate under an external force have an int…
A Mechanical Route for Cooperative Transport in Autonomous Robotic Swarms
Eden Arbel, Luco L. K. M. Buise, Charlotte C. R. M. M. van Waes +3
Cooperative transport is a striking phenomenon where multiple agents join forces to transit a payload too heavy for the individual. While social animals such as ants are routinely…
Hydrodynamic Spin-Pairing and Active Polymerization of Oppositely Spinning Rotors
Mattan Gelvan, Artyom Chirko, Jonathan Kirpitch +3
Rotors are common in nature - from rotating membrane-proteins to superfluid-vortices. Yet, little is known about the collective dynamics of heterogeneous populations of rotors. Her…
