This link is subtle due to the nonlinearities of general relativity. We show that considering a scattering process bypasses challenges with potential ambiguities, as the tidal response is determined by the asymptotic in- and outgoing waves at null infinity. As an application of the general method, we analyze scalar waves scattering off a nonspinning black hole and demonstrate that the low-frequency expansion of the tidal response reproduces known results for the Love number an","authors_text":"Gast\\'on Creci, Jan Steinhoff, Tanja Hinderer","cross_cats":["astro-ph.HE","astro-ph.SR","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2021-08-07T07:34:00Z","title":"Tidal response from scattering and the role of analytic continuation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2108.03385","kind":"arxiv","version":5},"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":"sha256:6d15406a119e5be01858a3cb824232a12d0c23a0768a243c89451edf2c41e39f","target":"record","created_at":"2026-07-05T05:09:48Z","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":"b751d34d2581c54f6dc1d244a5ba96249826eeba7cdcfe9142a1893a3f42d410","cross_cats_sorted":["astro-ph.HE","astro-ph.SR","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2021-08-07T07:34:00Z","title_canon_sha256":"5bac0adf87e3dec6b0d80878603ac3b35b9bbcedf11f9d5618373feddd5bbdbf"},"schema_version":"1.0","source":{"id":"2108.03385","kind":"arxiv","version":5}},"canonical_sha256":"672953342b84cd2a149d0f37f80301603ad5f1ff491be2c7b2299e32c0798b78","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"672953342b84cd2a149d0f37f80301603ad5f1ff491be2c7b2299e32c0798b78","first_computed_at":"2026-07-05T05:09:48.574087Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:09:48.574087Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GJ8GJscuuFKgj7MQsGIR08fWP7LVjHObg1xs+1Va0hBDALeVG7YM1bhmwpbvRjWcyxAtmRtWjekQcTmToh4EDg==","signature_status":"signed_v1","signed_at":"2026-07-05T05:09:48.574547Z","signed_message":"canonical_sha256_bytes"},"source_id":"2108.03385","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6d15406a119e5be01858a3cb824232a12d0c23a0768a243c89451edf2c41e39f","sha256:8654e56698a26fbf93f711ab8741e9afcb77e30f7f27184740adffcdb9caae92"],"state_sha256":"e0decf64d051e8395f7308fb14f14da1354336e0aa2c036fad954666ca51389b"}
