Spin dynamics simulations - a powerful method for the study of critical dynamics
D. P. Landau, Alex Bunker, Hans Gerd Evertz, M. Krech, Shan-Ho Tsai
Abstract
Spin-dynamics techniques can now be used to study the deterministic time-dependent behavior of magnetic systems containing over 105 spins with quite good accuracy. This approach will be introduced, including the theoretical foundations of the methods of analysis. Then newly developed, improved techniques based upon Suzuki-Trotter decomposition methods will be described. The current ``state-of-the-art'' will be evaluated with specific examples drawn from data on simple magnetic models. The examination of dynamic critical behavior will be highlighted but the extraction of information about excitations at low temperatures will be included.
