Exact Microscopic One-Body Reduction in the Symmetric Exclusion Process
Olivier Bénichou, Aurélien Grabsch
The symmetric exclusion process (SEP) is a paradigmatic model of interacting particle transport. Its current--density correlations are governed by an infinite many-body hierarchy o…
Transverse geometry reshapes current and tracer fluctuation amplitudes in quasi-one-dimensional single files
Olivier Bénichou, Aurélien Grabsch
Single-file transport means no overtaking: particles move in a narrow channel while preserving their longitudinal order. This simple constraint has profound dynamical consequences,…
Macroscopic fluctuation theory of interacting Brownian particles
Aurélien Grabsch, Davide Venturelli, Olivier Bénichou
We apply the macroscopic fluctuation theory (MFT) to study the large-scale dynamical properties of Brownian particles with arbitrary pairwise interaction. By combining it with stan…
Full stochastic dynamics of a tracer in a dense single-file system
Alexis Poncet, Aurélien Grabsch, Olivier Bénichou
Tracer diffusion in single-file systems, where particles are restricted to move on a line without passing each other, has been a fertile ground to investigate anomalous diffusion a…
Exact large-scale correlations in diffusive systems with general interactions: explicit characterisation without the Dean--Kawasaki equation
Aurélien Grabsch, Davide Venturelli, Olivier Bénichou
Characterising the statistical properties of classical interacting particle systems is a long-standing question. For Brownian particles the microscopic density obeys a stochastic e…
Dynamics of soft interacting particles on a comb
Davide Venturelli, Pierre Illien, Aurélien Grabsch +1
We study the dynamics of overdamped Brownian particles interacting through soft pairwise potentials on a comb-like structure. Within the linearized Dean-Kawasaki framework, we char…
