The Dirac point of the edge state cone is very close to the bulk valence band maximum. The Dirac cone is extremely anisotropic with a very large electron velocity along one diagonal of the surface elementary cell x' and a nearly flat dispersion in the perpendicular direction y'. The strong anisotropy originates from a broken fourfold rotoinversion symmetry at the surface.","authors_text":"Franc\\c{o}is Virot, Jeroen van den Brink, Manuel Richter, Roland Hayn","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2011-05-03T07:42:17Z","title":"Metacinnabar ({\\beta}-HgS): a strong 3D topological insulator with highly anisotropic surface states"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1105.0501","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":"sha256:361984153cd14c4f7ec75e3b63d683aa7fb652c8a760e786caecd264aa4a5284","target":"record","created_at":"2026-05-18T03:39:42Z","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":"29764e42aa0f94a6d7246c0eba7c3e7a4172f13f2aedc5e440742438d5af19d5","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2011-05-03T07:42:17Z","title_canon_sha256":"31db06b5fb7182a83ba72959faf8b4e203bda537db9969046f41b7a5509a524a"},"schema_version":"1.0","source":{"id":"1105.0501","kind":"arxiv","version":2}},"canonical_sha256":"b5d0bb6d147ceb70bd8cc37560f1d8d5d518abedb2f04092eaa506e0caeb5825","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b5d0bb6d147ceb70bd8cc37560f1d8d5d518abedb2f04092eaa506e0caeb5825","first_computed_at":"2026-05-18T03:39:42.021205Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:39:42.021205Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gx9k8oiFGGAFzIgaZM/OSmsSCbK3nLl+GBcxTa9DAjM77Yljy5G1598q8ET8vcTPfTqV3srw6ACelpvqfVX6Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:39:42.021903Z","signed_message":"canonical_sha256_bytes"},"source_id":"1105.0501","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:361984153cd14c4f7ec75e3b63d683aa7fb652c8a760e786caecd264aa4a5284","sha256:265e055c432c946afd0864edabb4900c932a9427ef1f6f53868f31ede6313132"],"state_sha256":"99110a03b532b5faf8c0910d26847bb47d1bf901eac1b23c1e167661e27a6f64"}
