An exclusion process with dynamic roadblocks

doi:10.1088/1674-1056/25/6/060505

Abstract

We study an exclusion process with multiple dynamic roadblocks. Each roadblock can move diffusively forward or backward with different rates, as well as unbind from/rebind to a free site. By Monte Carlo simulations, the two moving types are investigated in combination of roadblock number. The case of only diffusive roadblocks shows an asymmetric current-density relation. The case of only long-range jumping roadblocks presents that flux decreases with increasing roadblock number.

Keywords: exclusion process roadblocks diffusion unbinding/rebinding
