Key advances include the complete elementary band representation analyses of crystalline matter by symmetry indicators and the discovery of higher-order hinge and corner states. However, current classification schemes of such phases are either implicit or limited in scope. We present a new scheme for the explicit classification of crystalline topological insulators and superconductors. These phases are protected by crystallographic point group symmetries and are characterized by bulk topolog","authors_text":"Adam Chapman, Eyal Cornfeld","cross_cats":["cond-mat.mtrl-sci","cond-mat.str-el","cond-mat.supr-con","math-ph","math.MP"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-11-05T19:01:28Z","title":"Classification of Crystalline Topological Insulators and Superconductors with Point Group Symmetries"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.01977","kind":"arxiv","version":3},"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:e9008849cf5dcec0f305ace898bbd4d166d66fc1734b73a999e1223bf0ecfd65","target":"record","created_at":"2026-05-17T23:54:10Z","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":"f1385dc03732a6bfee9a4ca6b1bc642895ed18bdffa58d49495f1e42fcb8b6e8","cross_cats_sorted":["cond-mat.mtrl-sci","cond-mat.str-el","cond-mat.supr-con","math-ph","math.MP"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2018-11-05T19:01:28Z","title_canon_sha256":"3e9f07f743cf609cc80b4a40eca0b41b6bf972931eeab3b8f73195f26490ffc7"},"schema_version":"1.0","source":{"id":"1811.01977","kind":"arxiv","version":3}},"canonical_sha256":"debd1010481274b645b5d4baa43d0933e9ea21d7d534b204ef5d8a20e539ddb7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"debd1010481274b645b5d4baa43d0933e9ea21d7d534b204ef5d8a20e539ddb7","first_computed_at":"2026-05-17T23:54:10.609774Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:54:10.609774Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PN12wDydUedxDDGweQ0rICdoT1OIrvaIFgLqIXbUr3CN+lJyJeSd+AsfqqdUy1RjFPnrMjmj7uFuLJwqaAnmDQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:54:10.610402Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.01977","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9008849cf5dcec0f305ace898bbd4d166d66fc1734b73a999e1223bf0ecfd65","sha256:e0480810bf0e3c5e72f460a7ba81011b42afdbd680ab163bb7440f8db0441420"],"state_sha256":"865ff21cd7245f31e15138f18881c1257a0bf4dd440d65a8fc48238c63e17344"}
