Algorithms for faster and larger dynamic Metropolis simulations
M. A. Novotny, Alice K. Kolakowska, G. Korniss
In dynamic Monte Carlo simulations, using for example the Metropolis dynamic, it is often required to simulate for long times and to simulate large systems. We present an overview…
Discrete-Event Analytic Technique for Surface Growth Problems
A. Kolakowska, M. A. Novotny
We introduce an approach for calculating non-universal properties of rough surfaces. The technique uses concepts of distinct surface-configuration classes, defined by the surface g…
Angular Dependence of Switching Properties in Single Fe Nanopillars
G. Brown, S. M. Stinnett, M. A. Novotny +1
The continued increase in areal densities in magnetic recording makes it crucial to understand magnetization reversal in nanoparticles. We present finite-temperature micromagnetic…
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…
Virtual Time Horizon Control via Communication Network Design
Z. Toroczkai, G. Korniss, M. A. Novotny +1
We consider massively parallel discrete event simulations where the communication topology among the processing elements is a complex graph. In the case of regular topologies we re…
Suppressing Roughness of Virtual Times in Parallel Discrete-Event Simulations
G. Korniss, M. A. Novotny, H. Guclu +2
In a parallel discrete-event simulation (PDES) scheme, tasks are distributed among processing elements (PEs), whose progress is controlled by a synchronization scheme. For lattice…
Defects, Tunneling, and EPR Spectra of Single-Molecule Magnets
Kyungwha Park, M. A. Novotny, N. S. Dalal +5
We examine theoretically electron paramagnetic resonance (EPR) lineshapes as functions of resonance frequency, energy level, and temperature for single crystals of three different…
