We investigate the hybrid optomechanical cooling with a three-level atomic ensemble fixed in a strong excited optical cavity. By using the quantum noise approach, we find the upper bound of the noise spectrum and further present three optimal parameter conditions, which can yield a small heating coefficient, a large cooling coefficient, and thus a small final phonon number. Moreover, through the covariance matrix approach, results of numerical simulation are obtained, which are consistent with ","authors_text":"Feng-Guang Li, He-Liang Huang, Shuo Zhang, Tan Li, Wan-Su Bao, Xiang-Qun Fu, Xiang Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-06-03T06:21:32Z","title":"Ground state cooling in a hybrid optomechanical system with a three-level atomic ensemble"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.00899","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":"sha256:01481d5b78ec1721f4fa7f47696b47664e92bfeaa8f4acf75835518336cdcd56","target":"record","created_at":"2026-05-18T00:27:46Z","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":"0718bb2ca959a90f3acdf685d6f657c1ad1c28cc4ff1d0a0514be1218d8ffec3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-06-03T06:21:32Z","title_canon_sha256":"ec93322e9c3b82a64d3c5a5d2ac903c158694d951d9832daf031d239f6256658"},"schema_version":"1.0","source":{"id":"1706.00899","kind":"arxiv","version":3}},"canonical_sha256":"d112492af651e660ac9355e7659a0ae92179a5514310611e36d3155392d7a20d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d112492af651e660ac9355e7659a0ae92179a5514310611e36d3155392d7a20d","first_computed_at":"2026-05-18T00:27:46.529999Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:46.529999Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ki2zpJuQZhnuAZH3qXC9XLu4DqgnJdlOP3FLlDqNVYPkLL3GprWNcO0P8nFCdmyyBLzCbVrbrwiO7v41Ca2wCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:46.530511Z","signed_message":"canonical_sha256_bytes"},"source_id":"1706.00899","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:01481d5b78ec1721f4fa7f47696b47664e92bfeaa8f4acf75835518336cdcd56","sha256:344bdc8c33b7231b76d921e340af26a8075e1ca4efa28003e756e9f8080e73d4"],"state_sha256":"d413156670237ad2e97bac7ad9f8c34eb2f6e518116948272a5a36bd9bcd74f4"}
