We demonstrate that terahertz-driven four-wave mixing (FWM) at glass surfaces provides direct access to low-frequency vibrational modes and structural evolution in amorphous solids. Applied to a compositional series of PbO-silicate glasses (20-54 mol% PbO), this technique resolves distinct contributions from collective Boson-peak excitations and Pb-O / Si-O network stretching modes, and tracks their systematic evolution across structurally distinct compositio","authors_text":"Emmanuel Abraham, Eric Freysz, J\\'er\\^ome Degert, Laetitia Dalstein, Mathias Hedegaard Kristensen, Theo Guillaume","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2026-07-07T15:48:08Z","title":"Terahertz-driven four-wave mixing at glass surfaces: Probing vibrational resonances and structural regimes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.06417","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":"sha256:14ccb753cb8ceb277201f4abc852cb9fb8f4801ef0141fe71f9ef094afc70883","target":"record","created_at":"2026-07-08T01:19:24Z","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":"3ad0a88de8cf689c0c8db83dc6662c8d7f63609986d26a5119172d809760ec79","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2026-07-07T15:48:08Z","title_canon_sha256":"9c644cc6864e7125b5aef2d4129bb808f22f05cc7e77a3eb4d863ba977b3831e"},"schema_version":"1.0","source":{"id":"2607.06417","kind":"arxiv","version":1}},"canonical_sha256":"98ec333e3192ceb309bdacd325b329be84ed238ea9239b9c9a0747177eb86a12","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"98ec333e3192ceb309bdacd325b329be84ed238ea9239b9c9a0747177eb86a12","first_computed_at":"2026-07-08T01:19:24.784129Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-08T01:19:24.784129Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BtdBpdHX6xo2fAEauDnHGc7weNW2iLBtkMX5/eD8so40RLffZHq2B8dPdP5VhMg4+8LGAo1h14ThR0gvi+gEDQ==","signature_status":"signed_v1","signed_at":"2026-07-08T01:19:24.784631Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.06417","source_kind":"arxiv","source_version":1}}},"equivocations":[{"signer_id":"pith.science","event_type":"integrity_finding","target":"integrity","event_ids":["sha256:7938cb5f5d575a5806000207fdb55eca13407192b3980c4ed5202352f531fd0b","sha256:bde3dcdd499a5a0028c556366c4934bdb0205a9740a13957ff34370164d6c24f"]}],"invalid_events":[],"applied_event_ids":["sha256:14ccb753cb8ceb277201f4abc852cb9fb8f4801ef0141fe71f9ef094afc70883","sha256:1ba3546b6b2f13eadf036b70cd4313acd6c9a732b48cfce28f26e22e1e9a7ad1"],"state_sha256":"cc9ebd54df1593349b3db65e3e463402e973679a139c86a85a5cecc7cfe17ed1"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"MvhzwkF6D3AcF/9fmLLGD4gOxq6q2pRL5bbwAalzY1mck9ge+ZdugYxreNeLWQDZVb5LUJ0SDGtPS0ic8T6yCA==","signed_message":"bundle_sha256_bytes","signed_at":"2026-07-10T20:35:03.592878Z","bundle_sha256":"3402bb9a789fb1a637b18c4bf90bd9e74e00eba4cbcf542b9caa33e0d39776e9"}}
