Our mechanism relies on thermostatting the kinetic and configurational temperatures of the same particle differently. We keep the two ends of a conductor, which in the present study is a single dimensional $\\phi^4$ chain, at the same kinetic temperature $T_0$, but at different configurational temperatures - one end hotter and the other end colder than $T_","authors_text":"Baidurya Bhattacharya, Puneet Kumar Patra","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2016-03-28T03:55:22Z","title":"Heat pump without particle transport or external work on the medium achieved by differential thermostatting of the phase space"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.08295","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":"sha256:230876317324d89b7a92bd40f31278570331181797f7ec806fa1dae6ff75ec17","target":"record","created_at":"2026-05-18T01:18:11Z","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":"821920e1eab4a609d058f31536cf718d7d3ac2802ecf78b3069da2764f0fa8a0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2016-03-28T03:55:22Z","title_canon_sha256":"73260fbf9ad650915dd3b352eddba35a0a3a47ba90d38a0a59269a0ad7744fd7"},"schema_version":"1.0","source":{"id":"1603.08295","kind":"arxiv","version":1}},"canonical_sha256":"c6f338d59eeacb665e3901a1e8a8ec884c533e9103313273c491d42dbf80221c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c6f338d59eeacb665e3901a1e8a8ec884c533e9103313273c491d42dbf80221c","first_computed_at":"2026-05-18T01:18:11.098743Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:18:11.098743Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"RrAYu5N8jO9amb+lpIN/h2w9WHTauqHYlwXovpdgt3p3b6nEuwlnz06oA8dCc7lPoRRVPCwLSUDsICoVsWDsCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:18:11.099185Z","signed_message":"canonical_sha256_bytes"},"source_id":"1603.08295","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:230876317324d89b7a92bd40f31278570331181797f7ec806fa1dae6ff75ec17","sha256:6854ef8894a9d1eff74744ea5cce7bc7f5299358c5c37116df4bac9efa4b7445"],"state_sha256":"0bdc20081b750d2c33001198bfba8e0938cbc7d06228123a0a7bd8e8c100597e"}
