Fluctuations and universality in a catalysis model with long-range reactivity
C. H. Chan, P. A. Rikvold
The critical properties of the Ziff-Gulari-Barshad (ZGB) model with the addition of long-range reactivity [C.H. Chan and P.A. Rikvold, Phys. Rev. E 91, 012103 (2015)] are further i…
Model for the catalytic oxidation of CO, including gas-phase impurities and CO desorption
G. M. Buendia, P. A. Rikvold
We present results of kinetic Monte Carlo simulations of a modified Ziff-Gulari-Barshad model for the reaction CO+O --> CO_2 on a catalytic surface. Our model includes impurities i…
Role of dipolar and exchange interactions in the positions and widths of EPR transitions for the single-molecule magnets Fe8 and Mn12
Kyungwha Park, M. A. Novotny, N. S. Dalal +2
We examine quantitatively the temperature dependence of the linewidths and line shifts in electron paramagnetic resonance experiments on single crystals of the single-molecule magn…
Effect of Defects on the Line shape of Electron Paramagnetic Resonance Signals from the Single-Molecule Magnet Mn12: A Theoretical Study
Kyungwha Park, N. S. Dalal, P. A. Rikvold
We herein estimate the effect of lattice defects on the line shape of electron paramagnetic resonance (EPR) signals from a single crystal of the S=10 single-molecule magnet Mn$_{12…
Electron Paramagnetic Resonance Linewidths and Lineshapes for the Molecular Magnets Fe8 and Mn12
Kyungwha Park, M. A. Novotny, N. S. Dalal +2
We study theoretically Electron Paramagentic Resonance (EPR) linewidths for single crystals of the molecular magnets Fe and Mn as functions of energy eigenstates ,…
Dynamic Phase Transition in a Time-Dependent Ginzburg-Landau Model in an Oscillating Field
H. Fujisaka, H. Tutu, P. A. Rikvold
The Ginzburg-Landau model below its critical temperature in a temporally oscillating external field is studied both theoretically and numerically. As the frequency or the amplitude…
