It is found that multiple layers of Nos\\'e-Hoover heat bath are required to reduce the temperature jump at the boundary, while only a single layer of Langevin heat bath is sufficient to generate a linear temperature profile with small boundary temperature jump. Moreover, an intermediate value of heat bath parameter is recommended for both Nos\\'e-Hoover and Langevin heat bath in order to a","authors_text":"Baowen Li, Gang Zhang, Jie Chen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2010-05-25T04:32:58Z","title":"Molecular Dynamics Simulations of Heat Conduction in Nanostructures: Effect of Heat Bath"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1005.4481","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":"sha256:592a76fced66e81a3f0a9b5e67125aca3f586beedf9f1e3232f349daca0be636","target":"record","created_at":"2026-05-18T02:07:14Z","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":"b5b89696459cbc77f0376feb749dc2f78b91ca27eada88e03b9cc636e2ed9e21","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2010-05-25T04:32:58Z","title_canon_sha256":"1a1d87292c3cdf0682435453252b2ed25f14793430fb9dcb7b88ee2822c1bccc"},"schema_version":"1.0","source":{"id":"1005.4481","kind":"arxiv","version":1}},"canonical_sha256":"a8a536e96087a88bb7ffe48c89e66a7d3aa2c04eb1eb5eabd9449baefca68542","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a8a536e96087a88bb7ffe48c89e66a7d3aa2c04eb1eb5eabd9449baefca68542","first_computed_at":"2026-05-18T02:07:14.832698Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:07:14.832698Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CgEJyAM2ZgCyO1O9NU9ROt4/vvJU29XpuF/Yy6zQIOjW6TQC2XEON8nmqMumyLE2xlSTI8Y5l8G63nXU/LvRDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:07:14.833493Z","signed_message":"canonical_sha256_bytes"},"source_id":"1005.4481","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:592a76fced66e81a3f0a9b5e67125aca3f586beedf9f1e3232f349daca0be636","sha256:753a91afef2357312cd2175e0e5e1b131d8d96c7379e6204b5d83ee93682d733"],"state_sha256":"a8ab4533825d2526574893ee8ecd5d0e0c797798758da86d28b5f3de356730fd"}
