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…
Probing and modeling cell-cell communication in 2D biomimetic tissues
Cécile Marie Vincent, Sapna Ravindran, Alexis Michel Prevost +3
In tissues, cells in direct physical contact with each other can exchange ions or molecules via protein clusters called gap junctions that form channels across the membranes of adj…
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…
Time-dependent dynamics in the confined lattice Lorentz gas
A. Squarcini, A. Tinti, P. Illien +2
We study a lattice model describing the non-equilibrium dynamics emerging from the pulling of a tracer particle through a disordered medium occupied by randomly placed obstacles. T…
Joint distribution of currents in the symmetric exclusion process
Aurélien Grabsch, Pierre Rizkallah, Olivier Bénichou
The symmetric simple exclusion process (SEP) is a paradigmatic model of diffusion in a single-file geometry, in which the particles cannot cross. In this model, the study of curren…
Pair correlation of dilute Active Brownian Particles: from low activity dipolar correction to high activity algebraic depletion wings
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
We study the pair correlation of Active Brownian Particles at low density using numerical simulations and analytical calculations. We observe a winged pair correlation: while parti…
