Morphological computation and decentralized learning in a swarm of sterically interacting robots
Matan Yah Ben Zion, Jeremy Fersula, Nicolas Bredeche +1
Whereas naturally occurring swarms thrive when crowded, physical interactions in robotic swarms are either avoided or carefully controlled, thus limiting their operational density.…
Yield stress aging in attractive colloidal suspensions
Francesco Bonacci, Xavier Chateau, Eric Furst +2
We investigate the origin of yield stress aging in semi-dense, saline, and turbid suspensions in which structural evolution is rapidly arrested by the formation of thermally irreve…
Selective and Collective Actuation in Active Solids
P. Baconnier, D. Shohat, C. Hernandèz +4
Active solids consist of elastically coupled out-of-equilibrium units performing work. They are central to autonomous processes, such as locomotion, self-oscillations and rectifica…
Helfrich-Hurault elastic instabilities driven by geometrical frustration
Christophe Blanc, Guillaume Durey, Randall D. Kamien +3
The Helfrich-Hurault (HH) elastic instability is a well-known mechanism behind patterns that form as a result of strain upon liquid crystal systems with periodic ground states. In…
Programmed Wrapping and Assembly of Droplets with Mesoscale Polymers
Dylan M. Barber, Zhefei Yang, Lucas Prevost +4
Nature is remarkably adept at using interfaces to build structures, encapsulate reagents, and regulate biological processes. Inspired by Nature, we describe flexible polymer-based…
Crystal polymorph selection mechanism of hard spheres hidden in the fluid
Gabriele M. Coli, Robin van Damme, C. Patrick Royall +1
Nucleation plays a critical role in the birth of crystals and is associated with a vast array of phenomena such as protein crystallization and ice formation in clouds. Despite nume…
