The same interaction mechanisms produce strong collision rates in the normal phase of correlated metals, causing sizeable reductions of the dc conductivity and reflectivity. As a consequence, low-energy excitations like phonons, which are crucial for materials characterization, become visible in optical infrared spectra. A quantitative assessment of vibrational resonances requires the evaluation of dynamical Born effective charges, ","authors_text":"Francesco Macheda, Francesco Mauri, Guglielmo Marchese, Luca Binci, Matteo Calandra, Paolo Barone","cross_cats":["cond-mat.supr-con"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-03-01T18:54:24Z","title":"Born effective charges and vibrational spectra in super and bad conducting metals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.00741","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:e6511a31f7d38a392fabd3e0532468580adef619f04ea97f970841d47dcd3803","target":"record","created_at":"2026-07-05T11:11:29Z","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":"18802f7ffe98de1052e0dca9b6dca793d6c767719a3e5a2c794c68ac97c6f318","cross_cats_sorted":["cond-mat.supr-con"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2023-03-01T18:54:24Z","title_canon_sha256":"067e41b863753ba736490dd5b5432087758411f620205c5ffdea927b3556b8fe"},"schema_version":"1.0","source":{"id":"2303.00741","kind":"arxiv","version":5}},"canonical_sha256":"5bfd324b66bbec774ed91734c4fe063ceaa00ac87d88f665b3679ec191b378d3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5bfd324b66bbec774ed91734c4fe063ceaa00ac87d88f665b3679ec191b378d3","first_computed_at":"2026-07-05T11:11:29.462799Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:11:29.462799Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"isi67xa1S9RCOFehF1FPhyRBsYktZNODp5IC2N0ioqqiE9SgwGeiJWOiVWKtfpETM2ctmYV9y9b3fbsnN3fkAg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:11:29.463333Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.00741","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e6511a31f7d38a392fabd3e0532468580adef619f04ea97f970841d47dcd3803","sha256:cf0d6c08244e59c623b33e8c146c2a6aa93d2355774f4dccba918fac9bf237cb"],"state_sha256":"9a9d7d496c56c3b774ea71fbdaf195dfc2944fe1cfc57a74f4e9330090bffa87"}
