Scaling and super-universality in the coarsening dynamics of the 3d random field Ising model

We study the coarsening dynamics of the three-dimensional random field Ising model using Monte Carlo numerical simulations. We test the dynamic scaling and super-scaling properties of global and local two-time observables. We treat in parallel the three-dimensional Edward-Anderson spin-glass and we recall results on Lennard-Jones mixtures and colloidal suspensions to highlight the common and different out of equilibrium properties of these glassy systems.Comment: 18 pages, 21 figure

Monte Carlo simulations for statistical physics: Janus

Janus is an FPGA-based computer optimized for the simulation of spin glasses or similar condensed matter systems. Computing requirements in this area are still not met by available commercial systems, so an application-driven machine, boosting performance by approximately a factor 100x is in this case the only viable option to simulate large systems for a time window comparable with experiments
