An individual-based predator-prey model for biological coevolution: Fluctuations, stability, and community structure
Per Arne Rikvold, Volkan Sevim
We study an individual-based predator-prey model of biological coevolution, using linear stability analysis and large-scale kinetic Monte Carlo simulations. The model exhibits appr…
Complex Behavior in Simple Models of Biological Coevolution
Per Arne Rikvold
We explore the complex dynamical behavior of simple predator-prey models of biological coevolution that account for interspecific and intraspecific competition for resources, as we…
Reply to ``Remarks on the simulation of Cl electrosorption on Ag(100) reported in Electrochimica Acta 50 (2005) 5518"
P. A. Rikvold, Th. Wandlowski, I. Abou Hamad +2
We reply to remarks by Lang and Horanyi on the meaning of the notion of "electrosorption valency" used in I. Abou Hamad et al., Electrochim. Acta 50 (2005) 5518. It is concluded th…
First-order Reversal Curve Analysis of Phase Transitions in Electrochemical Adsorption: A New Experimental Technique Suggested by Computer Simulations
I. Abou Hamad, D. T. Robb, P. A. Rikvold
The first-order reversal curve (FORC) method for analysis of systems undergoing hysteresis is applied to dynamical models of electrochemical adsorption. In this setting, the method…
New Cyclic Voltammetry Method for Examining Phase Transitions: Simulated Results
I. Abou Hamad, D. T. Robb, P. A. Rikvold
We propose a new experimental technique for cyclic voltammetry, based on the first-order reversal curve (FORC) method for analysis of systems undergoing hysteresis. The advantages…
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…
Kinetic Monte Carlo simulations of electrodeposition: Crossover from continuous to instantaneous homogeneous nucleation within Avrami's law
Stefan Frank, Per Arne Rikvold
The influence of lateral adsorbate diffusion on the dynamics of the first-order phase transition in a two-dimensional Ising lattice gas with attractive nearest-neighbor interaction…
