Bath-modes quantitatively capture the nonlinear microrheology of micellar solutions
Pierre Champagnac, Clemens Bechinger, Juliana Caspers +3
Active microrheology experiments, in which a probe is driven through a complex fluid, often exhibit nonlinear responses that cannot be captured by generalized Langevin equations. M…
Universal wrinkling dynamics of a sheet on viscous liquid
Ayrton Draux, Marco Rizzo, Dominic Vella +3
We investigate the wrinkling dynamics of a thin elastic sheet that is indented or compressed while floating on a viscous liquid. We show that the deformation speed controls the dyn…
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…
Learning general pair interactions between self-propelled particles
Jérôme Hem, Alexis Poncet, Pierre Ronceray +2
Synthetic active matter systems, such as active colloids, often have complex interactions, which can be of hydrodynamic, chemical or electrostatic origin and cannot be computed fro…
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…
