It was found that the existence of a weak stochastic threshold has a significant impact on the cooling process, because below such a stochastic threshold the specific FPU energy is larger than its temperature, i.e., the FPU system falls out of equilibrium. The difference remains finite in the limit $T \\to 0$, so that the FPU system maintains a residual amount of energy $E_0$ ","authors_text":"Andrea Carati, Luigi Galgani, Matteo Razza","cross_cats":["physics.class-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2026-07-15T13:42:39Z","title":"Cooling rate and glassy behavior in the Fermi--Pasta--Ulam system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.13833","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:4625efe3093b9e552256ab100866b3660ed49a93c54737c2060724777823c37d","target":"record","created_at":"2026-07-16T01:23:08Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"edbe09b342bbaab266fe513ece323a25956db81acb0818d71df10cd7b1a86d4c","cross_cats_sorted":["physics.class-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2026-07-15T13:42:39Z","title_canon_sha256":"9fb8f2acab7ac927bab8db71ba676f0d6182263a145d043ee721c6a68f19305d"},"schema_version":"1.0","source":{"id":"2607.13833","kind":"arxiv","version":1}},"canonical_sha256":"5a98530875c0fff7c80e45b140bb8da2cc2e56cef7c8ef46745043a6ce5b8e8e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a98530875c0fff7c80e45b140bb8da2cc2e56cef7c8ef46745043a6ce5b8e8e","first_computed_at":"2026-07-16T01:23:08.749162Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-16T01:23:08.749162Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"W052k9+BRAy7ih8+vrlST5SoZi5nHU+JupP/hjs/fEapF43GDaS6L4MSln5M6zB9FdCNRo1n3hXegd+d+YufAg==","signature_status":"signed_v1","signed_at":"2026-07-16T01:23:08.750003Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.13833","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4625efe3093b9e552256ab100866b3660ed49a93c54737c2060724777823c37d","sha256:b85254d2526ca6819ea5ff8588aff492f20c1f18f04de41cfa093a5d245675dd"],"state_sha256":"e02c4a1b31126ce3b36aca54bd5d597c1d66894c33cca2c59f15477dadf45ddc"}
