Geometry still matters in quasi-one-dimensional single-file transport
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…
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…
Universal scale-free decay of tracer-bath correlations in -dimensional interacting particle systems
Davide Venturelli, Pierre Illien, Aurélien Grabsch +1
Quantifying the correlations between the position of a tagged tracer and the density of surrounding bath particles is crucial for understanding tracer diffusion in interacting part…
Tracer and current fluctuations in driven diffusive systems
Théotim Berlioz, Olivier Bénichou, Aurélien Grabsch
Interacting particles diffusing in single-file is a fundamental model of transport in narrow channels where particles cannot bypass each other. An important result has been obtaine…
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…
