Rucks and folds: delamination from a flat rigid substrate under uniaxial compression
Benny Davidovitch, Vincent Démery
We revisit the delamination of a solid adhesive sheet under uniaxial compression from a flat, rigid substrate. Using energetic considerations and scaling arguments we show that the…
Dynamics of a self-propelled particle in a harmonic trap
Olivier Dauchot, Vincent Démery
The dynamics of an active walker in a harmonic potential is studied experimentally, numerically and theoretically. At odds with usual models of self-propelled particles, we identif…
Cylinder morphology of a stretched and twisted ribbon
Vincent Démery, Huy Pham Dinh, Pascal Damman
A rich zoology of shapes emerges from a simple stretched and twisted elastic ribbon. Despite a lot of interest, all these shape are not understood, in particular the shape that pre…
Stresses in non-equilibrium fluids: Exact formulation and coarse grained theory
M. Krüger, A. Solon, V. Démery +2
Starting from the stochastic equation for the density operator, we formulate the exact (instantaneous) stress tensor for interacting Brownian particles, whose average value agrees…
From cylindrical to stretching ridges and wrinkles in twisted ribbons
Huy Pham Dinh, Vincent Démery, Benny Davidovitch +2
Twisted ribbons subjected to a tension exhibit a remarkably rich morphology, from smooth and wrinkled helicoids, to cylindrical or faceted patterns. These shapes are intimately rel…
Mean-field microrheology of a very soft colloidal suspension: inertia induces shear-thickening
Vincent Démery
Colloidal suspensions have a rich rheology and can exhibit shear-thinning as well as shear-thickening. Numerical simulations recently suggested that shear-thickening may be attribu…
Mechanics of large folds in thin interfacial films
Vincent Démery, Benny Davidovitch, Christian D. Santangelo
A thin film at a liquid interface responds to uniaxial confinement by wrinkling and then by folding; its shape and energy have been computed exactly before self contact. Here, we a…
Roadmap to the morphological instabilities of a stretched twisted ribbon
Julien Chopin, Vincent Démery, Benny Davidovitch
We address the mechanics of an elastic ribbon subjected to twist and tensile load. Motivated by the classical work of Green and a recent experiment that discovered a plethora of mo…
Electrostatic interactions mediated by polarizable counterions: weak and strong coupling limits
Vincent Démery, David S. Dean, Rudolf Podgornik
We investigate the statistical mechanics of an inhomogeneous Coulomb fluid composed of charged particles with static polarizability. We derive the weak- and the strong-coupling app…
The one dimensional Coulomb lattice fluid capacitor
Vincent Demery, David S. Dean, Thomas C. Hammant +2
The one dimensional Coulomb lattice fluid in a capacitor configuration is studied. The model is formally exactly soluble via a transfer operator method within a field theoretic rep…
Drag forces on inclusions in classical fields with dissipative dynamics
Vincent Demery, D. S. Dean
We study the drag force on uniformly moving inclusions which interact linearly with dynamical free field theories commonly used to study soft condensed matter systems. Drag forces…
