Improved mean field analysis of spontaneous symmetry breaking in a bidirectional two-lane system with narrow entrances

This Letter presents an improved mean field analysis of a bidirectional two-lane asymmetric exclusion process with narrow entrances, which exhibits spontaneous symmetry breaking. The method takes into account the correlation of the vertical cluster at system boundaries, which shows better agreement...

Description
Summary:This Letter presents an improved mean field analysis of a bidirectional two-lane asymmetric exclusion process with narrow entrances, which exhibits spontaneous symmetry breaking. The method takes into account the correlation of the vertical cluster at system boundaries, which shows better agreement with simulations than the simple mean field method.
