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…

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…
