Universidad de Zaragoza (orcid)0000-0002-5060-7658 Thermodynamic glass transition in a spin glass without time-reversal symmetry 2012 Access copy available to the general public Unrestricted Spin glasses are a longstanding model for the sluggish dynamics that appear at the glass transition. However, spin glasses differ from structural glasses in a crucial feature: they enjoy a time reversal symmetry. This symmetry can be broken by applying an external magnetic field, but embarrassingly little is known about the critical behavior of a spin glass in a field. In this context, the space dimension is crucial. Simulations are easier to interpret in a large number of dimensions, but one must work below the upper critical dimension (i.e., in d < 6) in order for results to have relevance for experiments. Here we show conclusive evidence for the presence of a phase transition in a four-dimensional spin glass in a field. Two ingredients were crucial for this achievement: massive numerical simulations were carried out on the Janus special-purpose computer, and a new and powerful finite-size scaling method. info:eu-repo/grantAgreement/ES/MICINN/FIS2009-12648-C03-02 info:eu-repo/grantAgreement/ES/MICINN/FIS2010-16587 info:eu-repo/grantAgreement/ES/MICINN/TEC2010-19207 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 9.737 2012 MULTIDISCIPLINARY SCIENCES 4 / 57 = 0.07 2012 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cruz, A.
