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…
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…
Evidence and quantification of memory effects in competitive first passage events
M. Dolgushev, T. V. Mendes, B. Gorin +6
Splitting probabilities quantify the likelihood of a given outcome out of competitive events. This key observable of random walk theory, historically introduced as the gambler's ru…
Current fluctuations in the symmetric exclusion process beyond the one-dimensional geometry
Théotim Berlioz, Davide Venturelli, Aurélien Grabsch +1
The symmetric simple exclusion process (SEP) is a paradigmatic model of transport, both in and out-of-equilibrium. In this model, the study of currents and their fluctuations has a…
