The Effect of Strong Symmetric Coupling on Two-Lane Totally Symmetric Simple Exclusion Process with Junction

We now study the effect of strong symmetric coupling on two-lane TASEP with junction in this paper. Our model focuses on the behavior and the effect of strong symmetric coupling existing before the junction. The investigation demonstrates that the phase diagram of our model includes five stationary phases (LD/LD [Low Density], HD/HD [High Density], MC [Maximum Current]/LD, LD/HD, and MC/HD phases), which likes the phase diagram of normal TASEP, namely the coordinates of triple points is (α = 0.5, β = 0.5). In conclusion, the phase diagram of our model is influenced by the lane changing behavior.
