(orcid)0000-0002-0007-8719 The Mpemba effect in spin glasses is a persistent memory effect 2019 Access copy available to the general public Unrestricted The Mpemba effect occurs when a hot system cools faster than an initially colder one, when both are refrigerated in the same thermal reservoir. Using the custom-built supercomputer Janus II, we study the Mpemba effect in spin glasses and show that it is a nonequilibrium process, governed by the coherence length xi of the system. The effect occurs when the bath temperature lies in the glassy phase, but it is not necessary for the thermal protocol to cross the critical temperature. In fact, the Mpemba effect follows from a strong relationship between the internal energy and xi that turns out to be a sure-tell sign of being in the glassy phase. Thus, the Mpemba effect presents itself as an intriguing avenue for the experimental study of the coherence length in supercooled liquids and other glass formers. info:eu-repo/grantAgreement/ES/DGA/FSE info:eu-repo/grantAgreement/EC/H2020/694925/EU/Low Temperature Glassy Systems/LoTGlasSy This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 694925-LoTGlasSy info:eu-repo/grantAgreement/EC/H2020/723955/EU/Universal explanation of low-temperature glass anomalies/GlassUniversality This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 723955-GlassUniversality info:eu-repo/grantAgreement/ES/MINECO/FIS2013-42840-P info:eu-repo/grantAgreement/ES/MINECO/FIS2015-65078-C2 info:eu-repo/grantAgreement/ES/MINECO/FIS2016-76359-P info:eu-repo/grantAgreement/ES/MINECO/MTM2014-56948-C2-2-P info:eu-repo/grantAgreement/ES/MINECO/MTM2017-84446-C2-2-R info:eu-repo/grantAgreement/ES/MINECO/TEC2016-78358-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.412 2019 MULTIDISCIPLINARY SCIENCES 7 / 70 = 0.1 2019 Q1 T1 5.165 2019 Multidisciplinary 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Calore, E.
