In this work we find proof of strong exciton-photon coupling in cavities formed by the layered crystals themselves, a phenomenon known as self-hybridization effect. We use multi-layers of high quality Ruddlesden-Popper perovskites in their 2D crystalline form, benefitting from their quantum-well excitonic resonances and the strong Fabry-Perot cavity modes resulting from the total-internal-reflection at their smoo","authors_text":"Finja Schillm\\\"oller, Maximilian Black, Mehdi Asadi, Nahid Talebi, Parsa Darman, Sara Darbari","cross_cats":["physics.optics"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-05-05T14:36:34Z","title":"Long-range self-hybridized exciton polaritons in two-dimensional Ruddlesden-Popper perovskites"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.02950","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":"sha256:31e7e6377e938b4eb569a91f0487ef6745dfa497bec6d783d7d8f1efeed7757d","target":"record","created_at":"2026-07-05T08:15:56Z","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":"52b3390f644845b272100b277a012a15f2bb8d4d4b4ee51bf70886a64199c541","cross_cats_sorted":["physics.optics"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2024-05-05T14:36:34Z","title_canon_sha256":"48053e82c92a1e16b5137515929518be26ee8ff8638b8275267459f014cf5d67"},"schema_version":"1.0","source":{"id":"2405.02950","kind":"arxiv","version":1}},"canonical_sha256":"29efc930fa6412385490778f3c208bf46b8dee444735008e6f69d4e038de6981","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"29efc930fa6412385490778f3c208bf46b8dee444735008e6f69d4e038de6981","first_computed_at":"2026-07-05T08:15:56.405890Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:15:56.405890Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IZ4iIiIisRoXqux9sEzLxLENXv/0UPL45eEbH7OGsVoFrYf8Za+monwzUQmVIjKd6VD8+B4jGUcx3B6+RgksBA==","signature_status":"signed_v1","signed_at":"2026-07-05T08:15:56.406518Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.02950","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:31e7e6377e938b4eb569a91f0487ef6745dfa497bec6d783d7d8f1efeed7757d","sha256:09b8c259c7af2bb001b84de127c15f90d1e3504ffc9aae75c5bf200e3a89a9b2"],"state_sha256":"1326e5c72ed8d39a5523bd0674573a8691a371cdb1bd5f75b18c5a519cb53ba9"}
