The coherent state considered is characterized by occupation numbers borrowed from the glasma fields produced in the early stages of high-energy nuclear collisions. The environment is modeled as the vacuum, and decoherence arises from the interaction of the state with vacuum fluctuations. We describe the system-environment interaction via a phase-damping model, which represents continuous measurements on the system withou","authors_text":"Gabriele Coci, Gabriele Parisi, Marco Ruggieri, Salvatore Plumari","cross_cats":["quant-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2025-07-07T09:26:23Z","title":"Entropy from decoherence: a case study using glasma-based occupation numbers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.04809","kind":"arxiv","version":2},"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":"sha256:63a939c449365c7313a2bc39d553d8e4885f19eea2ee2def69a4a2e72f0aa9b1","target":"record","created_at":"2026-07-05T11:38:08Z","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":"0074c1455d6a8b88b0c582b01d75b3a1f623304c3d8800dc895f81f2895e0383","cross_cats_sorted":["quant-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2025-07-07T09:26:23Z","title_canon_sha256":"4283644473e74993703b5505c1894d01813bf7e73bbdd1954110b227a9d9ccc5"},"schema_version":"1.0","source":{"id":"2507.04809","kind":"arxiv","version":2}},"canonical_sha256":"964bcdc81f0778c6800441507d35507fb8a483c7149b7fb928140e4ecab25443","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"964bcdc81f0778c6800441507d35507fb8a483c7149b7fb928140e4ecab25443","first_computed_at":"2026-07-05T11:38:08.691802Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:38:08.691802Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m1cdEjUkde2bPwj807f1f8oDQvTPyhgxEtLXvP9UYa+g8y3wV+vXQHwxj7cB56Hrl2VWpSCw/9RMpyZFZFyMAw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:38:08.692420Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.04809","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:63a939c449365c7313a2bc39d553d8e4885f19eea2ee2def69a4a2e72f0aa9b1","sha256:7ebd74ca1976f608fda841bfaf3adc7a9494b7a31db3cf9179acfe1d3da2e11f"],"state_sha256":"5d6f8aea91e0cca92ed2e0f3f7b92ad7f79a39cc89061bd27b4f519772ab8114"}
