Memory and rejuvenation effects in spin glasses are governed by more than one length scale 2023 Access copy available to the general public Unrestricted Memory and rejuvenation effects in the magnetic response of off-equilibrium spin glasses have been widely regarded as the doorway into the experimental exploration of ultrametricity and temperature chaos. Unfortunately, despite more than twenty years of theoretical efforts following the experimental discovery of memory and rejuvenation, these effects have, thus far, been impossible to reliably simulate. Yet, three recent developments convinced us to accept this challenge: first, the custom-built Janus II supercomputer makes it possible to carry out simulations in which the very same quantities that can be measured in single crystals of CuMn are computed from the simulation, allowing for a parallel analysis of the simulation and experimental data. Second, Janus II simulations have taught us how numerical and experimental length scales should be compared. Third, we have recently understood how temperature chaos materializes in aging dynamics. All these three aspects have proved crucial for reliably reproducing rejuvenation and memory effects on the computer. Our analysis shows that at least three different length scales play a key role in aging dynamics, whereas essentially all the theoretical analyses of the aging dynamics emphasize the presence and crucial role of a single glassy correlation length. info:eu-repo/grantAgreement/ES/AEI/PID2019-103939RB-I00 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/ES/MCIU/FPU18/02665 info:eu-repo/grantAgreement/ES/MICINN/PGC2018-094684-B-C22 info:eu-repo/grantAgreement/ES/MICINN/PID2021-125506NA-I00 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PGC2018-094684-B-C21 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PID2020-112936GB-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 18.1 2023 PHYSICS, MULTIDISCIPLINARY 5 / 112 = 0.045 2023 Q1 T1 8.228 2023 Physics and Astronomy (miscellaneous) 2023 Q1 30.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Calore, E.
