Using the Janus II custom-built supercomputer, the spin-glass correlation function is studied locally. Dramatic fluctuations are found when pairs of sites at the same distance are compared. The scaling of these fluctuations, as the spin-glass coherence length grows with time, is characterized through the computation of the singularity spectrum and its corresponding Legendre transform. A comparatively small number of site pairs controls the average correlation that governs the response to a magnetic field. We explain how this scenario of dramatic fluctuations (at length scales smaller than the coherence length) can be reconciled with the smooth, self-averaging behavior that has long been considered to describe spin-glass dynamics. info:eu-repo/grantAgreement/ES/MCIU/FPU18/02665 info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/PID2019-103939RB-I00 info:eu-repo/grantAgreement/ES/MICINN AEI/PID2020-112936GB-I00 info:eu-repo/grantAgreement/ES/MICINN AEI/PID2022-136374NB-C21 info:eu-repo/grantAgreement/ES/MICINN AEI/PID2022-136374NB-C22 info:eu-repo/grantAgreement/ES/MICINN/PGC2018-094684-B-C21 info:eu-repo/grantAgreement/ES/MICINN/PGC2018-094684-B-C22 info:eu-repo/grantAgreement/ES/MICINN/PID2021-125506NA-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 9.1 2024 MULTIDISCIPLINARY SCIENCES 14 / 136 = 0.103 2024 Q1 T1 3.414 2024 Multidisciplinary 2024 Q1 16.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Calore, Enrico Cruz, Andrés (orcid)0000-0002-7934-7271 Fernández, Luis Antonio Gil-Narvión, José Miguel (orcid)0000-0003-2903-3044 González-Adalid Pemartín, Isidoro Gordillo-Guerrero, Antonio Íñiguez, David (orcid)0000-0003-2916-5493 Maiorano, Andrea Marinari, Enzo Martín-Mayor, Víctor Moreno-Gordo, Javier (orcid)0000-0002-0420-8605 Muñoz Sudupe, Antonio Navarro, Denis Universidad de Zaragoza (orcid)0000-0002-0795-8743 Paga, Ilaria Parisi, Giorgio Pérez-Gaviro, Sergio Universidad de Zaragoza (orcid)0000-0001-8425-7345 Ricci-Tersenghi, Federico Ruiz-Lorenzo, Juan Jesús Schifano, Sebastiano Fabio Seoane, Beatriz Tarancón, Alfonso Universidad de Zaragoza (orcid)0000-0003-2772-3762 Yllanes, David (orcid)0000-0001-7276-2942 5008 785 Universidad de Zaragoza Dpto.
