Existence of spontaneous symmetry breaking in two-lane totally asymmetric simple exclusion processes with an intersection*

et al.

Abstract: We study two-lane totally asymmetric simple exclusion processes (TASEPs) with an intersection. Monte Carlo simulations show that only symmetric phases exist in the system. To verify the existence of asymmetric phases, we carry out a cluster mean-field analysis. Analytical results show that the densities of the two upstream segments of the intersection site are always equal, which indicates that the system is not in asymmetric phases. It demonstrates that the spontaneous symmetry breaking does not exist in the … Show more

“…Then, studies of ASEP with single lane have been generalized to ASEP with multilane which exhibits a variety of cooperative phenomena, such as shock formation, [12,13] phase separation, [14,15] and spontaneous symmetry breaking (SSB). [16][17][18][19][20] SSB is an interesting phenomenon in which symmetric conditions of the dynamic processes lead to existence of phases with broken symmetries. The phenomenon was first observed in the bridge model in which two species of particles move in the opposite directions in the single lane.…”

“…Motivated by this, cluster mean field analysis is often adopted, the correlation of sites is considered, and it performs much better than the simple mean field analysis. [17,18,20,24,25,27] Yuan et al have investigated totally asymmetric simple exclusion processes on two intersected lattices. [16] Three mod-els are studied.…”
