Spin Glass to Ferromagnet: Ageing Simulations on GPUs — •Markus Manssen1, Martin Weigel2, and Alexander K. Hartmann11Institut 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 [1] with computer simulations [2]. We broaden our view to the phase transition to the ferromagnet with the aid of Graphics Processing Units (GPUs) for long time simulations [3]. 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.
