Abstract
This paper studies asymmetric strong coupling effect in two parallel exclusion processes which is a generalization of previous works of Kolomeisky group Pronina and Kolomeisky in Physica A 37212 2006 Tsekouras and Kolomeisky in J Phys A 41465001 2008 It is shown that with different configurations of hopping rates the twolane system exhibits diverse phase diagram and density profiles Specifically it shows how the phase diagram changes from having seven phases via six phases to three phases Moreover it shows that the phase diagram could have only one phase which exhibits quadrilateral or triangular density profile The vertical cluster meanfield approach is used to get the stationarystate bulk densities and phase diagrams Extensively Monte Carlo simulations are carried out and theoretical predictions are in excellent agreement with simulation results
