Applications of Computer Simulations and Statistical Mechanics in Surface Electrochemistry (2009)
Rikvold, P. A., Hamad, I. Abou, Juwono, T., Robb, D. T., Novotny, M. A.
We present a brief survey of methods that utilize computer simulations and quantum and statistical mechanics in the analysis of electrochemical systems. The methods, Molecular Dynamics and Monte...
Evidence for a dynamic phase transition in [Co/Pt]_3 magnetic multilayers (2007)
Robb, D. T., Xu, Y. H., Hellwig, O., McCord, J., Berger, A., Novotny, M. A., ...
A dynamic phase transition (DPT) with respect to the period P of an applied alternating magnetic field has been observed previously in numerical simulations of magnetic systems. However, experimental...
Model of nanocrystal formation in solution by burst nucleation and diffusional growth (2007)
The phenomenon of burst nucleation in solution, in which a period of apparent chemical inactivity is followed by a sudden and explosive growth of nucleated particles from a solute species, has been...
Robb, D. T., Rikvold, P. A., Berger, A., Novotny, M. A.
The two-dimensional kinetic Ising model, when exposed to an oscillating applied magnetic field, has been shown to exhibit a nonequilibrium, second-order dynamic phase transition (DPT), whose order...
Hamad, I. Abou, Robb, D. T., Rikvold, P. A.
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 can not only...
New Cyclic Voltammetry Method for Examining Phase Transitions: Simulated Results (2006)
Hamad, I. Abou, Robb, D. T., Rikvold, P. A.
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 of this...
Finite-temperature Simulations for Magnetic Nanostructures (2005)
Novotny, M. A., Robb, D. T., Stinnett, S. M., Brown, G., Rikvold, P. A.
We examine different models and methods for studying finite-temperature magnetic hysteresis in nanoparticles and ultrathin films. This includes micromagnetic results for the hysteresis of a single...
FORC Analysis of homogeneous nucleation in the two-dimensional kinetic Ising model (2004)
Robb, D. T., Novotny, M. A., Rikvold, P. A.
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 homogeneous nucleation...
