The boundary-driven multispecies harmonic process
Francesco Casini, Rouven Frassek, Cristian Giardinà
We introduce the multispecies version of the harmonic process on a one-dimensional chain in contact with boundary reservoirs. This process is a continuous-time Markov chain where e…
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…
Intertwining and propagation of mixtures for generalized KMP models and harmonic models
Cristian Giardinà, Frank Redig, Berend van Tol
We study a class of stochastic models of mass transport on discrete vertex set . For these models, a one-parameter family of homogeneous product measures …
Duality for the multispecies stirring process with open boundaries
Francesco Casini, Rouven Frassek, Cristian Giardinà
We study the stirring process with species on a generic graph with reservoirs. The multispecies stirring process generalizes the symmetric exclusion proce…
