Effect of CO desorption and coadsorption with O on the phase diagram of a Ziff-Gulari-Barshad model for the catalytic oxidation of CO
G. M. Buendia, E. Machado, P. A. Rikvold
We study the effect of coadsorption of CO and O on a Ziff-Gulari-Barshad (ZGB) model with CO desorption (ZGB-d) for the reaction CO + O --> CO_2 on a catalytic surface. Coadsorptio…
Response of a Model of CO Oxidation with CO Desorption and Diffusion to a Periodic External CO Pressure
G. M. Buendia, E. Machado, P. A. Rikvold
We present a study of the dynamical behavior of a Ziff-Gulari-Barshad model with CO desorption and lateral diffusion. Depending on the values of the desorption and diffusion parame…
Decay of Metastable Nonequilibrium Phases, Enhanced Reaction Rate, and Dynamic Phase Transition in a Model of CO Oxidation with CO Desorption
E. Machado, G. M. Buendia, P. A. Rikvold +1
We present a computational study of the dynamic behavior of a Ziff-Gulari-Barshad model of CO oxidation with CO desorption on a catalytic surface. Our results provide further evide…
Decay of metastable phases in a model for the catalytic oxidation of CO
E. Machado, G. M. Buendia, P. A. Rikvold
We study by kinetic Monte Carlo simulations the dynamic behavior of a Ziff-Gulari-Barshad model with CO desorption for the reaction CO + O CO on a catalytic surface. Fini…
Response of a catalytic reaction to periodic variation of the CO pressure: Increased CO_2 production and dynamic phase transition
Erik Machado, Gloria M. Buendia, Per Arne Rikvold +1
We present a kinetic Monte Carlo study of the dynamical response of a Ziff-Gulari-Barshad model for CO oxidation with CO desorption to periodic variation of the CO presure. We use…
Compensation Temperature of a Mixed Ising Ferrimagnetic Model in the Presence of External Magnetic Fields
G. M. Buendia, E. Machado, M. A. Novotny
The behavior of the compensation temperature of a mixed Ising ferrimagnetic system on a square lattice in which the two interpenetrating square sublattices have spins ($\pm 1/2…
