Finite-Temperature Micromagnetics of Hysterisis for Misaligned Single Iron Nanopillars
M. A. Novotny, S. M. Stinnett, G. Brown +1
We present micromagnetic results for the hysterisis of a single magnetic nanopillar which is misaligned with respect to the applied magnetic field. We provide results for both a on…
Low-temperature nucleation in a kinetic Ising model with soft stochastic dynamics
Kyungwha Park, Per Arne Rikvold, Gloria M. Buendia +1
We study low-temperature nucleation in kinetic Ising models by analytical and simulational methods, confirming the general result for the average metastable lifetime, <tau> = A*exp…
Update statistics in conservative parallel discrete event simulations of asynchronous systems
A. Kolakowska, M. A. Novotny, Per Arne Rikvold
We model the performance of an ideal closed chain of L processing elements that work in parallel in an asynchronous manner. Their state updates follow a generic conservative algori…
Projective Dynamics Analysis of Magnetization Reversal
G. Brown, M. A. Novotny, P. A. Rikvold
The computational Projective Dynamics method is used to analyze simulations of magnetization reversal in nanoscale magnetic pillars. It is shown that this method can be used to det…
Punctuated equilibria and 1/f noise in a biological coevolution model with individual-based dynamics
Per Arne Rikvold, R. K. P. Zia
We present a study by linear stability analysis and large-scale Monte Carlo simulations of a simple model of biological coevolution. Selection is provided through a reproduction pr…
Flicker Noise in a Model of Coevolving Biological Populations
Per Arne Rikvold, R. K. P. Zia
We present long Monte Carlo simulations of a simple model of biological macroevolution in which births, deaths, and mutational changes in the genome take place at the level of indi…
