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. 000096050 536__ $$9info:eu-repo/grantAgreement/ES/DGA/FSE$$9info:eu-repo/grantAgreement/EC/H2020/694925/EU/Low Temperature Glassy Systems/LoTGlasSy$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 694925-LoTGlasSy$$9info:eu-repo/grantAgreement/EC/H2020/723955/EU/Universal explanation of low-temperature glass anomalies/GlassUniversality$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 723955-GlassUniversality$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2013-42840-P$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2015-65078-C2$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2016-76359-P$$9info:eu-repo/grantAgreement/ES/MINECO/MTM2014-56948-C2-2-P$$9info:eu-repo/grantAgreement/ES/MINECO/MTM2017-84446-C2-2-R$$9info:eu-repo/grantAgreement/ES/MINECO/TEC2016-78358-R 000096050 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000096050 590__ $$a9.412$$b2019 000096050 591__ $$aMULTIDISCIPLINARY SCIENCES$$b7 / 70 = 0.1$$c2019$$dQ1$$eT1 000096050 592__ $$a5.165$$b2019 000096050 593__ $$aMultidisciplinary$$c2019$$dQ1 000096050 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000096050 700__ $$aCalore, E. 000096050 700__ $$0(orcid)0000-0002-7934-7271$$aCruz, A.$$uUniversidad de Zaragoza 000096050 700__ $$aFernandez, L.A. 000096050 700__ $$0(orcid)0000-0003-2903-3044$$aGil-Narvion, J.M. 000096050 700__ $$aGordillo-Guerrero, A. 000096050 700__ $$0(orcid)0000-0003-2916-5493$$aIñiguez, D.$$uUniversidad de Zaragoza 000096050 700__ $$aLasanta, A. 000096050 700__ $$0(orcid)0000-0002-0340-5199$$aMaiorano, A. 000096050 700__ $$aMarinari, E. 000096050 700__ $$0(orcid)0000-0002-3376-0327$$aMartin-Mayor, V. 000096050 700__ $$0(orcid)0000-0002-0420-8605$$aMoreno-Gordo, J.$$uUniversidad de Zaragoza 000096050 700__ $$0(orcid)0000-0002-3613-3302$$aMuñoz Sudupe, A. 000096050 700__ $$0(orcid)0000-0002-0795-8743$$aNavarro, D.$$uUniversidad de Zaragoza 000096050 700__ $$aParisi, G. 000096050 700__ $$0(orcid)0000-0001-8425-7345$$aPerez-Gaviro, S.$$uUniversidad de Zaragoza 000096050 700__ $$aRicci-Tersenghi, F. 000096050 700__ $$aRuiz-Lorenzo, J.J. 000096050 700__ $$aSchifano, S.F. 000096050 700__ $$0(orcid)0000-0002-5967-2827$$aSeoane, B. 000096050 700__ $$0(orcid)0000-0003-2772-3762$$aTarancon, A.$$uUniversidad de Zaragoza 000096050 700__ $$aTripiccione, R. 000096050 700__ $$0(orcid)0000-0001-7276-2942$$aYllanes, D. 000096050 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
