In this work we report a special type of obstruction, known as orbital-mediated atomic obstruction, in monolayers of materials with spatial symmetry described by the space group $P$-$3m1$. By means of a minimal tight-binding model and first-principles calculations, we show that this obstructed phase is related to the mismatch of the charge centers coming from the atomic limit with respect to the cen","authors_text":"Leonor Chico, M\\'onica Pacheco, Olga Arroyo-Gasc\\'on, Sergio Bravo","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-12-12T18:46:48Z","title":"Two-dimensional orbital-obstructed insulators with higher-order band topology"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.09561","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":"sha256:22590ffb300d214b2d2256cf4c8817afcf5113f7805e967bb7cf69cc5cd2e4c6","target":"record","created_at":"2026-07-05T11:54:42Z","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":"3273665d512231c62de85bf067a86f0a0ae5cbc6e9dfa61c8fc3923ec778f989","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2024-12-12T18:46:48Z","title_canon_sha256":"37c0170a2e900e5bd3fdc74e4d93eccafc8879203d58bedb7ea54f2e625f0da1"},"schema_version":"1.0","source":{"id":"2412.09561","kind":"arxiv","version":2}},"canonical_sha256":"5bf4199222e99ae487ec05e5cbb89f5f530d45f3696c5c3f4a2871520c5274cd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5bf4199222e99ae487ec05e5cbb89f5f530d45f3696c5c3f4a2871520c5274cd","first_computed_at":"2026-07-05T11:54:42.952097Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:54:42.952097Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tHBJ1JYOoLteiBd5RuoW020FJRSnJ9E1KgpklzOh3Ry9bTwIGFfzRwNWSO4B9ZStRwdYq0E6/offrJ3Qqz2KDA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:54:42.952580Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.09561","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:22590ffb300d214b2d2256cf4c8817afcf5113f7805e967bb7cf69cc5cd2e4c6","sha256:211e7a2b771fd7f331506cf22b8c1773cbf6159a1c3d8b7ca066eb350aae5483"],"state_sha256":"3c89a9c177b14e5033afbdb67f8c4343d46bdd252dda3cffb6939d475af2f018"}
