Microstructure and velocity of field-driven solid-on-solid interfaces moving under stochastic dynamics with local energy barriers
G. M. Buendia, P. A. Rikvold, M. Kolesik
We study the microscopic structure and the stationary propagation velocity of (1+1)-dimensional solid-on-solid interfaces in an Ising lattice-gas model, which are driven far from e…
Effects of correlated interactions in a biological coevolution model with individual-based dynamics
Volkan Sevim, Per Arne Rikvold
Models of coevolution have recently been studied, in which a species is defined by a genome in the form of a bitstring, and the interactions between species i and j are given by a…
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…
Cl electrosorption on Ag(100): Lateral interactions and electrosorption valency from comparison of Monte Carlo simulations with chronocoulometry experiments
I. Abou Hamad, S. J. Mitchell, Th. Wandlowski +2
We present Monte Carlo Simulations using an equilibrium lattice-gas model for the electrosorption of Cl on Ag(100) single-crystal surfaces. Fitting the simulated isotherms to chron…
Fluctuations in models of biological macroevolution
Per Arne Rikvold
Fluctuations in diversity and extinction sizes are discussed and compared for two different, individual-based models of biological coevolution. Both models display power-law distri…
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…
