Spin Glass to Ferromagnet: Ageing Simulations on GPUs — •Markus Manssen1, Martin Weigel2, and Alexander K. Hartmann1 — 1Institut für Physik, Carl von Ossietzky Universität Oldenburg, Germany — 2Applied Mathematics Research Centre, Coventry University, England
The dynamics of spin glasses, frustrated magnetic systems, have been extensively studied  with computer simulations . We broaden our view to the phase transition to the ferromagnet with the aid of Graphics Processing Units (GPUs) for long time simulations . We focus on the three-dimensional binary Edwards-Anderson model and examine spatial and temporal correlations trying to explain them in terms of a growing dynamical correlation length.
