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…

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…
