Exact collective first-passage statistics of N trail-interacting walkers
Paul Pineau, Julien Brémont, Olivier Bénichou +1
The paper derives exact formulas for the first‑passage times and splitting probabilities of N one‑dimensional random walkers that interact through a shared, persistent trail field,…
Emergent memory in cell-like active systems
Marc Besse, Raphaël Voituriez
Active systems across scales, ranging from molecular machines to human crowds, are usually modeled as assemblies of self-propelled particles driven by internally generated forces.…
Adhesion differentials control the rheology of biomimetic emulsions
Quentin Guigue, Marc Besse, Raphael Voituriez +4
Animal morphogenesis involves complex tissue deformation processes, which require tight control over tissue rheology. Yet, it remains insufficiently understood how tissue rheology…
Flips Reveal the Universal Impact of Memory on Random Explorations
Julien Brémont, Léo Régnier, Alex Barbier--Chebbah +2
Quantifying space exploration is a central question in random walk theory, with direct applications ranging from animal foraging, diffusion-limited reactions, and intracellular tra…
First-Passage Observables of -dimensional Confined Jump Processes
Jérémie Klinger, Olivier Bénichou, Raphaël Voituriez
First-passage observables (FPO) are central to understanding stochastic processes in confined domains, with applications spanning chemical reaction kinetics, foraging behavior, and…
Persistence exponents of self-interacting random walks
Julien Brémont, Léo Régnier, Olivier Bénichou +1
The persistence exponent, which characterises the long-time decay of the survival probability of stochastic processes in the presence of an absorbing target, plays a key role in qu…
