One dimensional driven lattice gas of dimers coupled to on-off bulk kinetics — •Paolo Pierobon1,2, Thomas Franosch1,2, Mauro Mobilia1, and Erwin Frey1 — 1Arnold Sommerfeld Center, Theresienstr.37, D-80333 Muenchen — 2Hahn-Meitner Institut, Glienickerstr.100, D-14109 Berlin
We investigate the properties of a system that couples the Totally Asymmetric Simple Exclusion Process (TASEP) to the on/off kinetics in the bulk. We consider extended particles showing the robustness of the picture found in the case of monomers. We highlight analogies and differences between monomers and dimers using a refined mean field analysis (consistent with both the TASEP part and the on/off bulk kinetics) to rationalize the Monte Carlo data and derive the phase diagram. Furthermore we investigate the effect of the presence of a bottleneck in this kind of systems.
