The chiral surface states of a topological insulator(TI) selectively absorb right and left circularly polarized light in the vicinity of the Dirac cone reaching its maximum of unity at the $ \\Gamma $ point. In this letter, we demonstrate that a band gap open TI with C$_{2v}$ symmetry which is represented through a combination of Rashba and Dresselhaus Hamiltonians alters the preferential absorption of left and right circularly polarized light allowing a smooth variatio","authors_text":"Enrico Bellotti, Parijat Sengupta","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-08-19T22:54:53Z","title":"Tunable chirality and circular dichroism of a topological insulator with $ C_{2v} $ symmetry as a function of Rashba and Dresselhaus parameters"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1508.04825","kind":"arxiv","version":2},"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":"sha256:577d0dba3a3d859bdf6dd858d884e07b7160c1e903b79151b44d4384d69a23e8","target":"record","created_at":"2026-05-18T01:20:34Z","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":"1bba3e6cd2c63c2f53900298fafce33e368f8824cbc6aba4dbbef73835a56f1e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-08-19T22:54:53Z","title_canon_sha256":"8e1e3207c96724826587a120f5f8b9676444f765182d4177119d40e5621e9119"},"schema_version":"1.0","source":{"id":"1508.04825","kind":"arxiv","version":2}},"canonical_sha256":"d72dc54f595c81ba7f033ae8b727d88a5963a0062fcfc0890b9ac8b6cdf97654","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d72dc54f595c81ba7f033ae8b727d88a5963a0062fcfc0890b9ac8b6cdf97654","first_computed_at":"2026-05-18T01:20:34.517456Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:20:34.517456Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CX/gFqkhNg240l3XFVluUqdEgF7fgFUJzCWcq+oyQKieVqn4rAUd7Dy7JGwXzRFRAwR+SUKzRyaRM5QNw7mBDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:20:34.517965Z","signed_message":"canonical_sha256_bytes"},"source_id":"1508.04825","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:577d0dba3a3d859bdf6dd858d884e07b7160c1e903b79151b44d4384d69a23e8","sha256:9c44108276a8bc430afcbd09a57a19ce459e0bd22ce88dcf9aac737a9070f75e"],"state_sha256":"4e4c990d2b810e4bbc3427ea9268a6408d6aed95d5abd718e80c8528f81cfaa9"}
