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 [arXiv:2403.10359] and an intricate analysis of the deterministic approximation.", "revisions": [ { "version": "v1", "updated": "2025-06-20T17:30:52.000Z" } ], "analyses": { "subjects": [ "60B20", "82C10" ], "keywords": [ "random matrix model", "dynamical typicality", "random block-band matrix model", "achieve intermediate equilibration times", "wigner type random matrices" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
