Abstract
We study a totally asymmetric simple exclusion model with open boundar y conditions and a local inhomogeneity in the bulk. It consists of a o ne-dimensional lattice with particles hopping stochastically with equa l rates to the right at all lattice sites except one where the jump ra te is different. Approximate stationary-state solutions and phase diag rams are obtained and compared with Monte Carlo simulation results.
