Study of Adsorption Kinetics with the Zero Range Process — •Mark Paal¹, Henry Martin¹, and Matteo Colangeli² — ¹Kwame Nkrumah University of Science and Technology — ²University of L'Aquila

The Zero Range Process (ZRP) stands as a pivotal model in nonequilibrium statistical mechanics, offering profound insights into the macroscopic behaviour of systems driven away from equilibrium. This process, exemplifying driven diffusive systems on a lattice, unveils intricate phenomena including phase separation, transitions, and long-range correlations. In this study, we explore adsorption and desorption kinetics in confined geometries hoping it can provide insights into the behaviour of interacting particles. A discrete hopping model, such as the zero-range process, can be used to investigate these kinetics even on a one-dimensional lattice.
