By inserting a nanotip into the cavity mode, we estimate that the cavity dissipation rate increases by a factor of approximately 20, due to the scattering loss at the tip. As applications of our in-situ technique, we demonstrate that an exceptional line can be obtained when a single atom or ion is coupled to the resonator. Moreover, the position of an exceptional point is tuned by adjusting the decay rate, enabling a topological transition through dissipation control alone.","authors_text":"Donggeon Kim, Dowon Lee, Eunchul Jeong, Jinuk Kim, Kiyanoush Goudarzi, Moonjoo Lee, Myunghun Kim, Taegyu Ha, Uijin Kim","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-06-09T14:27:22Z","title":"In-situ tuning of cavity dissipation and a topological transition in an atom-nanotip-cavity system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.07800","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":"sha256:0c88edc1cad356f1f971e51c16d64c654f1b29d3d6140391a9899ebb32de19b6","target":"record","created_at":"2026-07-05T11:18:33Z","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":"02cc9101a9f968d29e82247800a8380c80976b556c84928b94960f8c7dafc4f6","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-06-09T14:27:22Z","title_canon_sha256":"cb6d0ad1764e31f0a14dd912eb0a45578515c1e32425aab2936c12b9a962c2fb"},"schema_version":"1.0","source":{"id":"2506.07800","kind":"arxiv","version":1}},"canonical_sha256":"da82b35e9a756092c20d68936c36a9b7029046f210b93a887850d3c9bd77652f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"da82b35e9a756092c20d68936c36a9b7029046f210b93a887850d3c9bd77652f","first_computed_at":"2026-07-05T11:18:33.642787Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:18:33.642787Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JJHMxvsaWQIJvoolwItpL4OOg+QgpjcY7H2i7xBClgQgfmhhVug+L73SneQxBWmXY9dL4pvuztadVBRpF4LtBw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:18:33.643353Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.07800","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0c88edc1cad356f1f971e51c16d64c654f1b29d3d6140391a9899ebb32de19b6","sha256:68474e5f457b894498fe351c896f87bbc4bfba3c9e4bac74ecbf65d81f4dc635"],"state_sha256":"173b188f6e650cf2362604e680920cd67f56ec842184717e388b2c44e2567b05"}
