-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…
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…
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…
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 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…
