Sculpting liquids with ultrathin shells
Yousra Timounay, Alexander R. Hartwell, Mengfei He +4
Thin elastic films can spontaneously attach to liquid interfaces, offering a platform for tailoring their physical, chemical, and optical properties. Current understanding of the e…
Pair correlation of dilute Active Brownian Particles: from low activity dipolar correction to high activity algebraic depletion wings
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
We study the pair correlation of Active Brownian Particles at low density using numerical simulations and analytical calculations. We observe a winged pair correlation: while parti…
Colloidal transport in bacteria suspensions: from bacteria scattering to anomalous and enhanced diffusion
Antoine Lagarde, Noémie Dagès, Takahiro Nemoto +3
Colloids coupled to a bath of swimming cells generically display enhanced diffusion. This transport dynamics stems from a subtle interplay between the active and passive particles…
Bath-Mediated Interactions between Driven Tracers in Dense Single-Files
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
Single-file transport, where particles cannot bypass each other, has been observed in various experimental setups. In such systems, the behaviour of a tracer particle (TP) is subdi…
Driven probe under harmonic confinement in a colloidal bath
Vincent Démery, Étienne Fodor
Colloids held by optical or magnetic tweezers have been used to explore the local rheological properties of a complex medium and to extract work from fluctuations with some appropr…
Mechanical factors affecting the mobility of membrane proteins
Vincent Démery, David Lacoste
The mobility of membrane proteins controls many biological functions. The application of the model of Saffman and Delbrück to the diffusion of membrane proteins does not account fo…
Geometry underlies the mechanical stiffening and softening of an indented floating film
Monica M. Ripp, Vincent Démery, Teng Zhang +1
A basic paradigm underlying the Hookean mechanics of amorphous, isotropic solids is that small deformations are proportional to the magnitude of external forces. However, slender b…
Memory effects in the ion conductor RbTiO
Rémi Federicci, Stéphane Holé, Vincent Démery +1
Recent studies on Rb2Ti2O5 crystals have demonstrated remarkable electrical properties. This material exhibits colossal electrical polarization between 200 K and 330 K. In the pres…
Pinning by rare defects and effective mobility for elastic interfaces in high dimensions
Xiangyu Cao, Vincent Démery, Alberto Rosso
The existence of a depinning transition for a high dimensional interface in a weakly disordered medium is controversial. Following Larkin arguments and a perturbative expansion, on…
Elastic interactions in damage models of brittle failure
Vincent Démery, Véronique Dansereau, Estelle Berthier +2
The failure of brittle solids involves, before macroscopic rupture, power-law distributed avalanches of local rupture events whereby microcracks nucleate and grow, which are also o…
Geometry-driven folding of a floating annular sheet
Joseph D. Paulsen, Vincent Démery, K. Buğra Toga +4
Predicting the large-amplitude deformations of thin elastic sheets is difficult due to the complications of self-contact, geometric nonlinearities, and a multitude of low-lying ene…
Phase diagram of a bulk 1d lattice Coulomb gas
V. Démery, R. Monsarrat, D. S. Dean +1
The exact solution, via transfer matrix, of the simple one dimensional lattice Coulomb gas (1d LCG) model can reproduce peculiar features of ionic liquid capacitors, such as oversc…
The conductivity of strong electrolytes from stochastic density functional theory
Vincent Démery, David S Dean
Stochastic density functional theory is applied to analyze the conductivity of strong two species electrolytes at arbitrary field strengths. The corresponding stochastic equations…
Generalized Langevin equations for a driven tracer in dense soft colloids: construction and applications
Vincent Démery, Hugo Jacquin, Olivier Bénichou
We describe a tracer in a bath of soft Brownian colloids by a particle coupled to the density field of the other bath particles. From the Dean equation, we derive an exact equation…
Effect of disorder geometry on the critical force in disordered elastic systems
Vincent Démery, Vivien Lecomte, Alberto Rosso
We address the effect of disorder geometry on the critical force in disordered elastic systems. We focus on the model system of a long-range elastic line driven in a random landsca…
Aspects of One-Dimensional Coulomb Gases
Ronald R. Horgan, David S. Dean, Vincent Démery +3
In this short review, we discuss recent advances in exact solutions of models based on a one- dimensional (1D) Coulomb gas by means of field-theoretic functional integral methods.…
