Uphill transport in competitive drift-diffusion models with volume exclusion
Francesco Casini, Cristian Giardinà, Jacopo Nicolini +2
This paper addresses uphill transport (defined as a regime in which particle flow is opposite to the prescriptions of Fick's diffusion) in drift-diffusion particle transport constr…

Convergence of the KMP model to the KPZ equation
Guillaume Barraquand, Francesco Casini
We prove that the Kipnis-Marchioro-Presutti (KMP) process converges to the Kardar-Parisi-Zhang (KPZ) equation, as time goes to infinity, in a properly scaled observation window…

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…
