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…
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…
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…
