A key feature of our model is that we achieve intermediate equilibration times, an aspect that has not been proven rigorously in any model before. Our proof builds on recently established concentration estimates for products of resolvents of Wigner type random matrices (Erdős and Riabov in Commun Math Phys 405(12): 282, 2024) and an intricate analysis of the deterministic approximation.","lang":"eng"}],"year":"2025","author":[{"last_name":"Erdös","full_name":"Erdös, László","first_name":"László","orcid":"0000-0001-5366-9603","id":"4DBD5372-F248-11E8-B48F-1D18A9856A87"},{"id":"31d731d7-d235-11ea-ad11-b50331c8d7fb","orcid":"0000-0003-1106-327X","first_name":"Sven Joscha","full_name":"Henheik, Sven Joscha","last_name":"Henheik"},{"full_name":"Vogel, Cornelia","first_name":"Cornelia","last_name":"Vogel","id":"1cd0554a-ea28-11f0-9f40-ff76440883cd"}],"corr_author":"1","article_type":"original","status":"public","publication":"Letters in Mathematical Physics","intvolume":"       116","oa_version":"Published Version","ec_funded":1,"scopus_import":"1","day":"26","volume":116,"project":[{"name":"Random matrices beyond Wigner-Dyson-Mehta","_id":"62796744-2b32-11ec-9570-940b20777f1d","call_identifier":"H2020","grant_number":"101020331"}],"OA_type":"hybrid","has_accepted_license":"1","PlanS_conform":"1","_id":"20925","date_published":"2025-12-26T00:00:00Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"pmid":["41459414"]},"article_number":"5","date_updated":"2026-01-05T11:22:25Z","publisher":"Springer Nature","ddc":["510"]}
