Cellular-automaton approach to a surface reaction

Abstract
A cellular-automaton model for a surface reaction is introduced that describes the chemical reactions correctly. The phase-transition points and the order of the phase transitions agree well with the results of Ziff, Gulari, and Barshad via a Monte Carlo simulation [Phys. Rev. Lett. 56, 2553 (1986)]. The high performance of the cellular automaton leads to a more precise determination of the critical exponent β at the second-order phase transition (β=0.58), which thus appears to belong to the universality class of Reggeon field theory.
