(orcid)0000-0002-0007-8719 Dynamical transition in the D=3 Edwards-Anderson spin glass in an external magnetic field 2014 Access copy available to the general public Unrestricted We study the off-equilibrium dynamics of the three-dimensional Ising spin glass in the presence of an external magnetic field. We have performed simulations both at fixed temperature and with an annealing protocol. Thanks to the Janus special-purpose computer, based on field-programmable gate array (FPGAs), we have been able to reach times equivalent to 0.01 s in experiments. We have studied the system relaxation both for high and for low temperatures, clearly identifying a dynamical transition point. This dynamical temperature is strictly positive and depends on the external applied magnetic field. We discuss different possibilities for the underlying physics, which include a thermodynamical spin-glass transition, a mode-coupling crossover, or an interpretation reminiscent of the random first-order picture of structural glasses info:eu-repo/grantAgreement/EC/FP7/247328/EU/Critical Phenomena in Random Systems/CRIPHERASY info:eu-repo/grantAgreement/ES/MEC/FIS2006-08533 info:eu-repo/grantAgreement/ES/MICINN/FIS2010-16587 info:eu-repo/grantAgreement/ES/MICINN/TEC2010-19207 info:eu-repo/grantAgreement/ES/MINECO/FIS2012-35719-C02 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.288 2014 PHYSICS, MATHEMATICAL 5 / 54 = 0.093 2014 Q1 T1 PHYSICS, FLUIDS & PLASMAS 9 / 31 = 0.29 2014 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Baños, R.A.
