Non-Equilibrium Collective Transport on Molecular Highways
Résumé
Intracellular motion driven by motor proteins on cytoskeletal filaments provides an interesting example for studying non-equilibrium transport phenomena. We will discuss a 3-dimensional lattice gas model, based on the generalization of a totally asymmetric exclusion process with non conserved dynamics (TASEP coupled with Langmuir Kinetics). In particular, we will focus on emergent physical properties, specific to the three-dimensional geometry, concerning traffic jam and phase separation phenomena, with interesting biological implications for real intracellular transport processes.
