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…
Reconfiguration, Interrupted Aging and Enhanced Dynamics of a Colloidal Gel using Photo-Switchable Active Doping
Mengshi Wei, Matan Ben Zion, Olivier Dauchot
We study light-activated quasi-2d gels made of a colloidal network doped with Janus particles. Following the gel formation, the internal dynamics of the gel are monitored before, d…
Hydrodynamic spin-orbit coupling in asynchronous optically driven micro-rotors
Matan Yah Ben Zion, Alvin Modin, Paul M. Chaikin
Vortical flows of rotating particles describe interactions ranging from molecular machines to atmospheric dynamics. Yet to date, direct observation of the hydrodynamic coupling bet…
Hyperuniformity and phase enrichment in vortex and rotor assemblies
Naomi Oppenheimer, David B. Stein, Matan Yah Ben Zion +1
Ensembles of particles rotating in a two-dimensional fluid can exhibit chaotic dynamics yet develop signatures of hidden order. Such "rotors" are found in the natural world spannin…
