Active pistons extract work by periodic compression alone

Paul Bernard, Euijoon Kwon, Benjamin Buhl +2

Active matter is liable to invent protocols that evade the constraints of equilibrium thermodynamics. We put forward active pistons that extract work by periodic compression alone…

From Active to Odd to Smart Matter

Olivier Dauchot

The study of active matter has reshaped our understanding of collective states of matter far from equilibrium by proving that energy pumped into the microscopic scale leads to orde…

Theory of collective learning in populations of adaptive agents

Gerhard Jung, Johann Asnacios, Misaki Ozawa +2

We investigate homogeneous populations of smart active agents that exchange information with their neighbors to perform a decentralized learning process aimed at achieving a prescr…

Aggregating swarms through morphology handling design contingencies: from the sweet spot to a rich expressivity

Jeremy Fersula, Nicolas Bredeche, Olivier Dauchot

Morphological computing, the use of the physical design of a robot to ease the realization of a given task has been proven to be a relevant concept in the context of swarm robotics…

Pogobot: an Open-Source, Low-Cost Robot for Swarm Robotics and Programmable Active Matter

Alessia Loi, Loona Macabre, Jérémy Fersula +8

This paper describes the Pogobot, an open-source platform specifically designed for research at the interface of swarm robotics and active matter. Pogobot features vibration-based…

Collective actuation in active solids in the presence of a polarizing field: a systematic analysis of the dynamical regimes

Paul Baconnier, Vincent Démery, Olivier Dauchot

Collective actuation in active solids, the spontaneous condensation of the dynamics on a few elastic modes, takes place whenever the deformations of the structure reorient the forc…

Reentrant transition to collective actuation in active solids with a polarizing field

Paul Baconnier, Mathéo Aksil, Vincent Démery +1

Collective actuation in active solids - the spontaneous coherent excitation of a few vibrational modes - emerges from a feedback between structural deformations and the orientation…

Tuning collective actuation of active solids by optimizing activity localization

Davi Lazzari, Olivier Dauchot, Carolina Brito

Active solids, more specifically elastic lattices embedded with polar active units, exhibit collective actuation when the elasto-active feedback, generically present in such system…

Traveling Fronts and the Smoothing of the Collective-Motion Phase Transition in Vibrated Polar Disks

Caleb J. Anderson Olivier Dauchot, Alberto Fernandez-Nieves

One of the most well known features of active matter is the tendencey of self-propelled particles to undergo system-wide collective motion. With low enough rotational noise or high…

Self-Aligning Polar Active Matter

Paul Baconnier, Olivier Dauchot, Vincent Démery +4

Self-alignment describes the property of a polar active unit to align or anti-align its orientation towards its velocity. In contrast to mutual alignment, where the headings of mul…

Self-Aligning Active Agents with Inertia and Active Torque

Jeremy Fersula, Nicolas Bredeche, Olivier Dauchot

We extend the study of the inertial effects on the dynamics of active agents to the case where self-alignment is present. In contrast with the most common models of active particle…

Dynamical Facilitation Governs the Equilibration Dynamics of Glasses

Rahul N. Chacko, François P. Landes, Giulio Biroli +3

Convincing evidence of domain growth in the heating of ultrastable glasses suggests that the equilibration dynamics of super-cooled liquids could be driven by a nucleation and grow…

Noise-Induced Collective Actuation in Active Solids

Paul Baconnier, Vincent Démery, Olivier Dauchot

Collective actuation describes the spontaneous synchronized oscillations taking place in active solids, when the elasto-active feedback, that generically couples the reorientation…

No net motion for oscillating near-spheres at low Reynolds numbers

Kevin Lippera, Olivier Dauchot, Sébastien Michelin +1

We investigate the flow around an oscillating nearly-spherical particle at low, yet non-vanishing, Reynolds numbers, and the potential resulting locomotion. We analytically demonst…

Shear modulus and Dilatancy Softening in Granular Packings above Jamming

Corentin Coulais, Antoine Seguin, Olivier Dauchot

We investigate experimentally the mechanical response of a monolayer of bi-disperse frictional grains to an inhomogeneous shear perturbation across the jamming transition. We infla…

Contacts Dynamics Reveals Widom Lines for Jamming

C. Coulais, R. P. Behringer, O. Dauchot

We experimentally study the vicinity of the Jamming transition by investigating the statics and the dynamics of the contact network of an horizontally shaken bi-disperse packing of…
