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…
Reversal Modes of Simulated Iron Nanopillars in an Obliquely Oriented Field
S. H. Thompson, G. Brown, P. A. Rikvold
Stochastic micromagnetic simulations are employed to study switching in three-dimensional magnetic nanopillars exposed to highly misaligned fields. The switching appears to proceed…
FORC Analysis of homogeneous nucleation in the two-dimensional kinetic Ising model
D. T. Robb, M. A. Novotny, P. A. Rikvold
The first-order reversal curve (FORC) method is applied to the two-dimensional kinetic Ising model. For the system size and magnetic field chosen, the system reverses by the homoge…
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…
Projective Dynamics in Realistic Models of Nanomagnets
S. H. Thompson, G. Brown, P. A. Rikvold
The free-energy extrema governing the magnetization-reversal process for a model of an iron nanopillar are investigated using the projective dynamics method. Since the time evoluti…
Low-temperature nucleation in a kinetic Ising model under different stochastic dynamics with local energy barriers
Gloria M. Buendia, Per Arne Rikvold, Kyungwha Park +1
Using both analytical and simulational methods, we study low-temperature nucleation rates in kinetic Ising lattice-gas models that evolve under two different Arrhenius dynamics tha…
