By deriving exact integral solutions for the second-order correlation function, we demonstrate that counter-rotating magnon-photon interactions induce quadrature squeezing in the cavity mode. Furthermore, we show that tuning the anisotropic magnon-cavity couplings enhances the squeezing effect by changing the level repulsion of the magnon-cavity photon hybrid m","authors_text":"Alireza Qaiumzadeh, Arne Brataas, Vemund Falch","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-11-27T16:59:41Z","title":"Second-order correlation and squeezing of photons in cavities with ultrastrong magnon-photon interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2411.18512","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":"sha256:91235d7cfa44295e7faa4985761a4b6d2e9478e209ae8ad97b68c3b804965c6e","target":"record","created_at":"2026-07-05T10:41:50Z","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":"5486154233458d08a1ec726853ff1465642f842139aa2c1f14f188e14ecc4307","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-11-27T16:59:41Z","title_canon_sha256":"81fa45962091f45540425ba33fe133bd9f5eb44f15210243482310299762fa76"},"schema_version":"1.0","source":{"id":"2411.18512","kind":"arxiv","version":3}},"canonical_sha256":"af1ea997b78811ee643ce4ba0aa3980eedc5bb8f59bfcccebf30c774aecea1b8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"af1ea997b78811ee643ce4ba0aa3980eedc5bb8f59bfcccebf30c774aecea1b8","first_computed_at":"2026-07-05T10:41:50.649362Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:41:50.649362Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"juGBh+0dv1lSYoN8Ig1GTmCmNK9O+wLbY9OpqFjR3Kp6i3qnIt2hwtY9blmvrc6vJusd7cVwBnjwh34AtFaUBg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:41:50.649877Z","signed_message":"canonical_sha256_bytes"},"source_id":"2411.18512","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:91235d7cfa44295e7faa4985761a4b6d2e9478e209ae8ad97b68c3b804965c6e","sha256:6241a38bbca1756383b7a394030e3905cea5894c7cf627efe24da3cdbadb872d"],"state_sha256":"5583ee4c359f7105a74d890177ac3156bb0601a65556d1e41b9e1965ec79cb64"}
