摘要: Department of Chemistry, Rice University, Houston, Texas 77005-1892, USA~Received 11 February 2003; published 27 June 2003!We study the formation localized shocks in one-dimensional driven diffusive systems with spatiallyhomogeneous creation and annihilation particles ~Langmuir kinetics!. We show how to obtain hydrodynamicequations that describe density profile uncorrelated steady state as well thoseexhibiting correlations. As a special example latter case, Katz-Lebowitz-Spohn model is considered.The existence double shock demonstrated systems.This corresponds phase separation into regimes three distinct densities, separated by domainwalls. Our analytical approach supported Monte Carlo simulations.DOI: 10.1103/PhysRevE.67.066117 PACS number~s!: 05.70.Ln, 64.60.Ht, 02.50.Ga, 47.70.2nI. INTRODUCTION
