Single on-Ramp in Asymmetric Simple Exclusion Processes

This paper studies the single on-ramp in a totally asymmetric simple exclusion processes (TASEPs). In our model, particles can only attach irreversibly with rate q to a bulk site k + 1, which is far away from boundaries. The model is investigated under random sequential update and open boundary conditions by using Monte Carlo simulations and mean-field calculations. In the case of hopping rate p = 1, when attachment rate q is fixed and q < 0.5, there are five phases in the system, while when q > 0.5, the system includes only four phases and the LD/LD phase vanishes.
