Phase diagrams and free-energy landscapes for model spin-crossover materials with antiferromagnetic-like nearest-neighbor and ferromagnetic-like long-range interactions
Chor-Hoi Chan, Gregory Brown, Per Arne Rikvold
We present phase diagrams, free-energy landscapes, and order-parameter distributions for a model spin-crossover material with a two-step transition between the high-spin and low-sp…
Density of states for systems with multiple order parameters: a constrained Wang-Landau method
Chor-Hoi Chan, Gregory Brown, Per Arne Rikvold
A macroscopically constrained Wang-Landau Monte Carlo method was recently proposed to calculate the joint density of states (DOS) for systems with multiple order parameters. Here w…
Equilibrium, Metastability, and Hysteresis in a Model Spin-crossover Material with Nearest-neighbor Antiferromagnetic-like and Long-range Ferromagnetic-like Interactions
P. A. Rikvold, G. Brown, S. Miyashita +2
Phase diagrams and hysteresis loops were obtained by Monte Carlo simulations and a mean-field method for a simplified model of a spin-crossover material with a two-step transition…
Numerical Confirmation of Late-time t^{1/2} Growth in Three-dimensional Phase Ordering
Gregory Brown, Per Arne Rikvold
Results for the late-time regime of phase ordering in three dimensions are reported, based on numerical integration of the time-dependent Ginzburg-Landau equation with nonconserved…
Monte Carlo Methods for Equilibrium and Nonequilibrium Problems in Interfacial Electrochemistry
Gregory Brown, Per Arne Rikvold, S. J. Mitchell +1
We present a tutorial discussion of Monte Carlo methods for equilibrium and nonequilibrium problems in interfacial electrochemistry. The discussion is illustrated with results from…
Simulated Dynamics of Underpotential Deposition of Cu with Sulfate on Au(111)
Gregory Brown, Per Arne Rikvold, M. A. Novotny +1
Numerical studies of lattice-gas models are well suited to describe multi-adsorbate systems. One example is the underpotential deposition of Cu on Au(111) in the presence of sulfur…
