Here we propose a detuning-switched method that can rapidly generate strong and stationary mechanical squeezing. The pulsed driving can dynamically transpose the optomechanical coupling into a linear optical force and maintain an effective mechanical frequency, which can introduce strong mechanical squeezing in a short time. Moreover, we show the obtained strong mechanical squeezing can be frozen by increasing the pulse inter","authors_text":"An-Ning Xu, Long-Gang Huang, Yaohua Li, Yong-Chun Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-03-08T10:04:39Z","title":"Mechanical Squeezing via Detuning-Switched Driving"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.04482","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":"sha256:3ab1d157f0f54a9576ba4ffe46f3ca0cdad90886e9e92adad064139479f25aa3","target":"record","created_at":"2026-07-05T05:52:27Z","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":"c2023fec26b4c45ac2e98f5c3dfa8d41212112c6a88ab0053fa9a5099d4035f9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-03-08T10:04:39Z","title_canon_sha256":"25292a05b7657137de02ab3e8e9eb5219b99da3f3a82b71620166b8ae9fbe476"},"schema_version":"1.0","source":{"id":"2303.04482","kind":"arxiv","version":1}},"canonical_sha256":"a43a63a00adcbbeca1954568daef78be316a374e1ad14e4b48c170e148d75e57","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a43a63a00adcbbeca1954568daef78be316a374e1ad14e4b48c170e148d75e57","first_computed_at":"2026-07-05T05:52:27.661350Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:52:27.661350Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"t55guP5PZcXL9uyPlH54qC7kmgyPvsTOEQeFC9W99Pg/DVqynomnIRGzHgSe2AVT1Dzm62srwm9N/6/IxbJmBA==","signature_status":"signed_v1","signed_at":"2026-07-05T05:52:27.661833Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.04482","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3ab1d157f0f54a9576ba4ffe46f3ca0cdad90886e9e92adad064139479f25aa3","sha256:a2cf40d45e2d0663c4d48809121a9eb28a76eca86c587dfeb9c1e01c5c78a034"],"state_sha256":"96ae1330fe2ba1fb34b67dab6b52178bd6e5590c61dd2fc692c6cb9d1ed6e325"}
