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…
-tag Probability Law of the Symmetric Exclusion Process
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
The Symmetric Exclusion Process (SEP), in which particles hop symmetrically on a discrete line with hard-core constraints, is a paradigmatic model of subdiffusion in confined syste…
Fault orientation in damage failure under compression
Véronique Dansereau, Vincent Démery, Estelle Berthier +2
The Mohr-Coulomb criterion is widely used in geosciences to relate the state of stress at failure to the observed orientation of the resulting faults. This relation is based on the…
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…
Unbinding transition of probes in single-file systems
Olivier Bénichou, Vincent Démery, Alexis Poncet
Single-file transport, arising in quasi one-dimensional geometries where particles cannot pass each other, is characterized by the anomalous dynamics of a probe, notably its respon…
Universal Long Ranged Correlations in Driven Binary Mixtures
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
When two populations of "particles" move in opposite directions, like oppositely charged colloids under an electric field or intersecting flows of pedestrians, they can move collec…
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…
Diffusion of a particle quadratically coupled to a thermally fluctuating field
Vincent Démery
We study the diffusion of a Brownian particle quadratically coupled to a thermally fluctuating field. In the weak coupling limit, a path-integral formulation allows to compute the…
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…
Out of equilibrium thermal Casimir effect in a model polarizable material
David S. Dean, Vincent Démery, V. Adrian Parsegian +1
Relaxation of the thermal Casimir or van der Waals force for a model dielectric medium is investigated. We start with a model of interacting polarization fields with a dynamics tha…
Overscreening in 1D lattice Coulomb gas model of ionic liquids
Vincent Demery, David S. Dean, Thomas C. Hammant +2
Overscreening in the charge distribution of ionic liquids at electrified interfaces is shown to proceed from purely electrostatic and steric interactions in an exactly soluble one…
Thermal Casimir drag in fluctuating classical fields
V. Démery, D. S. Dean
A uniformly moving inclusion which locally suppresses the fluctuations of a classical thermally excited field is shown to experience a drag force which depends on the dynamics of t…
A perturbative path integral study of active and passive tracer diffusion in fluctuating fields
V. Démery, D. S. Dean
We study the effective diffusion constant of a Brownian particle linearly coupled to a thermally fluctuating scalar field. We use a path integral method to compute the effective di…
Diffusion of active tracers in fluctuating fields
David S. Dean, V. Demery
The problem of a particle diffusion in a fluctuating scalar field is studied. In contrast to most studies of advection diffusion in random fields we analyze the case where the part…
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…
Drag forces in classical fields
Vincent Demery, David S. Dean
Inclusions, or defects, moving at constant velocity through free classical fields are shown to be subject to a drag force which depends on the field dynamics and the coupling of th…
