Analytic Approximations for the Velocity of Field-Driven Ising Interfaces
Per Arne Rikvold, M. Kolesik
We present analytic approximations for the field, temperature, and orientation dependences of the interface velocity in a two-dimensional kinetic Ising model in a nonzero field. Th…
Micromagnetic simulations of thermally activated magnetization reversal of nanoscale magnets
Gregory Brown, M. A. Novotny, Per Arne Rikvold
Numerical integration of a stochastic Landau-Lifshitz-Gilbert equation is used to study dynamic processes in single-domain nanoscale magnets at nonzero temperatures. Special attent…
From Massively Parallel Algorithms and Fluctuating Time Horizons to Non-equilibrium Surface Growth
G. Korniss, Z. Toroczkai, M. A. Novotny +1
We study the asymptotic scaling properties of a massively parallel algorithm for discrete-event simulations where the discrete events are Poisson arrivals. The evolution of the sim…
Evolution of speckle during spinodal decomposition
Gregory Brown, Per Arne Rikvold, Mark Sutton +1
Time-dependent properties of the speckled intensity patterns created by scattering coherent radiation from materials undergoing spinodal decomposition are investigated by numerical…
Dynamic Phase Transition and Hysteresis in Kinetic Ising Models
P. A. Rikvold, G. Korniss, C. J. White +2
We briefly introduce hysteresis in spatially extended systems and the dynamic phase transition observed as the frequency of the oscillating field increases beyond a critical value.…
