摘要: Abstract This Letter investigates the effect of unequal injection rates on two-lane simple exclusion processes with asymmetric coupling. It is a generalization work Pronina and Kolomeisky [E. Pronina, A.B. Kolomeisky, Physica A 372 (2006) 12], in which two lanes are equal. With rate α 1 increases, ( , LD ) HD MC phase region do not change, while 0 regions shrink expand. Interestingly, domain walls observed both when system phase. However, have little wall dynamics. The diagram density profiles investigated by using Monte Carlo simulations mean-field approximation. analytical results good agreement simulations.
