Asymmetric exclusion process with global hopping
Résumé
We study a one-dimensional totally asymmetric simple exclusion process with one special site from which particles $fly$ to $any$ empty site (not just to the neighboring site). The system attains a non-trivial stationary state with density profile varying over the spatial extent of the system. The density profile undergoes a non-equilibrium phase transition when the average density passes through the critical value $1-[4(1-ln 2)]^{-1}=0.185277$..., viz. in addition to the discontinuity in the vicinity of the special site, a shock wave is formed in the bulk of the system when the density exceeds the critical density.
