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…
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…
Dimensional crossover via confinement in the lattice Lorentz gas
A. Squarcini, A. Tinti, P. Illien +2
We consider a lattice model in which a tracer particle moves in the presence of randomly distributed immobile obstacles. The crowding effect due to the obstacles interplays with th…
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…
