The topological insulator Bi2Se3 represents a natural hyperbolic optical medium, both in the THz and visible range. Here, using cathodoluminescence spectroscopy and electron energy-loss spectroscopy, we demonstrate that Bi2Se3, in addition to being a hyperbolic material, supports room-temperature exciton polaritons. Moreover, we explore the behavior of hyperbolic edge exciton polaritons in Bi2Se3. Edge polaritons are hybrid modes that result from the coupling of the polaritons boun","authors_text":"Bruno Gompf, Harald Giessen, Mario Hentschel, Marko Burghard, Nahid Talebi, Peter A. van Aken, Robin Lingstaedt, Soudabeh Mashhadi","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.app-ph","submitted_at":"2020-10-15T08:50:09Z","title":"Interaction of edge exciton polaritons with engineered defects in the van der Waals material Bi2Se3"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2010.07601","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:feabfc8977b22851efa9f96f44865e899683d055fdc48af6ac20e4d9d68d072e","target":"record","created_at":"2026-07-05T02:08:32Z","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":"be1faac5bd97e83d21cc2a05a6152e2a0faa6343a9392317cbf3f7a004b74f64","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.app-ph","submitted_at":"2020-10-15T08:50:09Z","title_canon_sha256":"72787cef773912a848c12172c87ffb170ec25f0caee40b3b374c5a0ab48a16c4"},"schema_version":"1.0","source":{"id":"2010.07601","kind":"arxiv","version":1}},"canonical_sha256":"e45972a1bd5c9c554037bd2abb1d3e3b5aef8f801fac5cd45aed45604e62239f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e45972a1bd5c9c554037bd2abb1d3e3b5aef8f801fac5cd45aed45604e62239f","first_computed_at":"2026-07-05T02:08:32.009305Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:08:32.009305Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U8R18CY6jlv8fWL5RBcPNnfuCL9YRRykCKLzNoUcLmSEpfN2xO0KYiY/4EMPvC4CGiLedoaBErmgyK0VUGTPCA==","signature_status":"signed_v1","signed_at":"2026-07-05T02:08:32.009701Z","signed_message":"canonical_sha256_bytes"},"source_id":"2010.07601","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:feabfc8977b22851efa9f96f44865e899683d055fdc48af6ac20e4d9d68d072e","sha256:3435ee642da5c802f1a03288bc82926806e75f2aa686a3ad976b1c87589e6448"],"state_sha256":"ae3d89bd1c1d7f015490bb285d71a2dac45347cf8a9b21ee21e4b19ad18f8c81"}
