Hydrodynamic limit and large deviations for run-and-tumble particles with mean-field switching rates
Elena Pulvirenti, Frank Redig, Hidde van Wiechen
In this paper, we study run-and-tumble particles moving on two copies of the discrete torus (referred to as layers), where the switching rate between layers depends on a mean-field…

A large deviation principle for the multispecies stirring process
Francesco Casini, Frank Redig, Hidde van Wiechen
In this paper we consider the multispecies stirring process on the discrete torus. We prove a large deviation principle for the trajectory of the vector of densities of the differe…
