The initial state of the quantized mechanical oscillator plays a key role. As the initial mean amplitude of the oscillator decreases, the resulting efficiency increases. In contrast to laser-powered self-induced oscillations, work extraction from a broadband heat bath does not require coherence or phase-locking: an initial phase-averaged coherent state of the oscillator still yields work, as opposed to an initial Fock-state.","authors_text":"David Gelbwaser-Klimovsky, Gershon Kurizki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-10-30T21:14:23Z","title":"Work extraction from heat-powered quantized optomechanical setups"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.8561","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:d6d2c3aaebc118fc71100c0e90b16779f76edb0b5ac14bd46b370c6332f1b616","target":"record","created_at":"2026-05-18T02:28:13Z","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":"277c83ffe6f1c60fcdedf24d7c44ecc14758cea0e3598299d32d2fa0bf65d465","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-10-30T21:14:23Z","title_canon_sha256":"95edb4427413ba029a806ea87ab01ab88dd3d26093387f6cf31c0deac4226947"},"schema_version":"1.0","source":{"id":"1410.8561","kind":"arxiv","version":2}},"canonical_sha256":"6e9a9dc7452c56e1fb77e15353f4fbbef89d3511a6d84711665898ebef10b360","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6e9a9dc7452c56e1fb77e15353f4fbbef89d3511a6d84711665898ebef10b360","first_computed_at":"2026-05-18T02:28:13.228525Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:28:13.228525Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Tko56XF5hMs9XW5/8rQ+2klJFD1wmjB7mZP1sRuN38e2NaeIx9ocge1cZuct28VeP4bLYmKfeNn1j6FfefBcAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:28:13.228925Z","signed_message":"canonical_sha256_bytes"},"source_id":"1410.8561","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d6d2c3aaebc118fc71100c0e90b16779f76edb0b5ac14bd46b370c6332f1b616","sha256:2332c9ae28b8b1f86bc3c47aae9759816b199aa52f888908c50a1386ca176cd9"],"state_sha256":"6635fdf166df05b6a54a0ed29fba3a820670b71dbf078ea0877213473f2f0cbb"}
