Blockage induced condensation controlled by a local reaction
arXiv:1609.06334 · doi:10.1103/PhysRevE.94.042116
Abstract
We consider the set-up of stationary Zero Range models and discuss the onset of condensation induced by a local blockage on the lattice. We show that the introduction of a local feedback on the hopping rates allows to control the particle fraction in the condensed phase. This phenomenon results in a current vs. blockage parameter curve characterized by two non--analyticity points.
