The temperature is kept constant by a contact with a heat bath, realised via a stochastic momentum-preserving noise added to the dynamics. The noise is designed to be large at the microscopic level, but vanishing in the macroscopic scale. Boundary conditions are also considered: one end of the chain is kept fixed, while a time-varying tension is applied to the other end. We show that the volume stretch and momentum converge (in an appropriate sense) to a","authors_text":"Stefano Marchesani, Stefano Olla","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.PR","submitted_at":"2018-02-06T14:32:57Z","title":"Hydrodynamic Limit for an Anharmonic Chain under Boundary Tension"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.01965","kind":"arxiv","version":3},"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":"sha256:81d17190afd6c4174069661610febd95767065ba9e63e02bf6fbac29f4edfa09","target":"record","created_at":"2026-05-17T23:45:10Z","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":"5b74033d63ab6001e6d4660ec458aa7bb5068d4bf348b1a5ea1ff9090871dd48","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.PR","submitted_at":"2018-02-06T14:32:57Z","title_canon_sha256":"96d8134755a47889e5a7e60175202ad6c5ce4718bb4402c62d1451307ab5794b"},"schema_version":"1.0","source":{"id":"1802.01965","kind":"arxiv","version":3}},"canonical_sha256":"23f2061dfc687919f7e1ef2167ff428d6a5dd313cf99494cbbf0cb1429708d95","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"23f2061dfc687919f7e1ef2167ff428d6a5dd313cf99494cbbf0cb1429708d95","first_computed_at":"2026-05-17T23:45:10.026716Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:10.026716Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8ag9AD75EzLefyZCzt7XR8yCMxR7yq3fJkZdaU3q6Ahz3PUJSUtrMAw5d5BxVbssXPHCf4Z87+4DrQErhJytDw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:10.027278Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.01965","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:81d17190afd6c4174069661610febd95767065ba9e63e02bf6fbac29f4edfa09","sha256:e02c7b41f7df06cda9d093187f2cb491c576089abc546e939929526f5f425914"],"state_sha256":"beddca80b9513c75041f49e02cc8bef96e15f87fd33ed83ae5ef7a6936224daf"}
