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…
Shape of a membrane on a liquid interface with arbitrary curvatures
Zachariah S. Schrecengost, Seif Hejazine, Jordan V. Barrett +2
We study the deformation of a liquid interface with arbitrary principal curvatures by a flat circular sheet. Working first at small slopes, we determine the shape of the sheet anal…
Nonlinear conductivity of aqueous electrolytes: beyond the first Wien effect
Hélène Berthoumieux, Vincent Démery, A. C. Maggs
The conductivity of strong electrolytes increases under high electric fields, a nonlinear response known as the first Wien effect. Here, using molecular dynamics simulations we sho…
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…
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…
Enhanced diffusion of tracer particles in nonreciprocal mixtures
Anthony Benois, Marie Jardat, Vincent Dahirel +4
We study the diffusivity of a tagged particle in a binary mixture of Brownian particles with non-reciprocal interactions. Numerical simulations reveal that, for a broad class of in…
Interplay of gross and fine structures in strongly-curved sheets
Mengfei He, Vincent Démery, Joseph D. Paulsen
Although thin films are typically manufactured in planar sheets or rolls, they are often forced into three-dimensional shapes, producing a plethora of structures across multiple le…
