In the case of Schwarzschild and Kerr black holes, this property has been shown to be a consequence of a hidden structure of ladder symmetries for the perturbations. In this work, we extend the ladder symmetries to non-rotating charged black holes in general relativity. As opposed to previous works in this context, we adopt a more general definition of Love numbers, including quadratic operators that mix gravitational and electromagnetic perturbations in the point-particle effective f","authors_text":"Luca Santoni, Mudit Rai","cross_cats":["hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2024-04-09T18:00:30Z","title":"Ladder Symmetries and Love Numbers of Reissner--Nordstr\\\"om Black Holes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2404.06544","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:d4bacc5f1dd915c4b1124dbfbada4a833028c8cce419c1918550256b5d288236","target":"record","created_at":"2026-07-05T08:44:13Z","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":"39ba9bfd7a011d3d75f2f2ac46955de56922b646c90b99acb0cf54998f2b47cf","cross_cats_sorted":["hep-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2024-04-09T18:00:30Z","title_canon_sha256":"dc0a62d6c642c4e0bd260980d9b50aa1e7dc74820b1d4c25eb39622cc8b8fb83"},"schema_version":"1.0","source":{"id":"2404.06544","kind":"arxiv","version":2}},"canonical_sha256":"ed1bc46ea10fc465f7197e9476fdbfb2b49427e49303cebc21db22e863b26782","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ed1bc46ea10fc465f7197e9476fdbfb2b49427e49303cebc21db22e863b26782","first_computed_at":"2026-07-05T08:44:13.601480Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:44:13.601480Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZL73DT+2H5oURN1W0jt4KKF4EScqVoxCk46iEDjLhNpB3wAvok66r5gkh8p9VasmRu8+5JConProatFW8+yUCA==","signature_status":"signed_v1","signed_at":"2026-07-05T08:44:13.601901Z","signed_message":"canonical_sha256_bytes"},"source_id":"2404.06544","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d4bacc5f1dd915c4b1124dbfbada4a833028c8cce419c1918550256b5d288236","sha256:fb9932f3c099a2a366aa1975eb76ba099ae3e545301b13a00ba3474c90154deb"],"state_sha256":"8d5ad1e9281c5f2ac2457f8719738e3c9203bf25c5a6d9116d70d1ac094cfe84"}
