The study of hydrodynamic phonon transport has spanned over half a century but has been mostly limited to cryogenic temperatures (~1 K) and more recently to low-dimensional materials. Here, we identify graphite as a three-dimensional material that supports phonon hydrodynamics at significantly higher temperatures (~100 K) based on first-principles calculations. In particular, by solving the Boltzmann equation for phonon transport in graphite ribb","authors_text":"Bai Song, Gang Chen, Jiawei Zhou, Mingda Li, Te-Huan Liu, Vazrik Chiloyan, Zhiwei Ding","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-11-02T01:45:13Z","title":"Phonon Hydrodynamic Heat Conduction and Knudsen Minimum in Graphite"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.00587","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":"sha256:40ee67a799d4c1f6897ae1749ef770a09026f0c6e792090c6f5ee66f152b2473","target":"record","created_at":"2026-05-18T00:24:35Z","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":"81b8980b8a685c4e5e61eea8bd8e85d4aa377588b222b68e2b8112cfbe5d8dab","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2017-11-02T01:45:13Z","title_canon_sha256":"e19d4bfdaa352066a6fb30e70490d97e80db846a079b8548c8f90a5f8f3f537a"},"schema_version":"1.0","source":{"id":"1711.00587","kind":"arxiv","version":2}},"canonical_sha256":"776789b82e807186a0a829147b083468a41de12392f2fb7ffc6a9b76f14225e8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"776789b82e807186a0a829147b083468a41de12392f2fb7ffc6a9b76f14225e8","first_computed_at":"2026-05-18T00:24:35.036966Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:24:35.036966Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BhBUMU/qL6DJWP0T2T6zU5e5eSSvLL5V+1vBFlr/aDF+cNhNG/bS9NTK72X7uOQmlkaHO+UZ6u7cq2FndXaiDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:24:35.037378Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.00587","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:40ee67a799d4c1f6897ae1749ef770a09026f0c6e792090c6f5ee66f152b2473","sha256:3218e14071a1e3b3a4e86ba6d681927d48fc50f14552d445a8448070ff937563"],"state_sha256":"04215143cf8bf314b0ec0c9d87b6fe20c75094aad8e0040fbf4bf926ca8ffe39"}
