A popular reconstruction approach called discrete tomography confines the atom locations to a coarse spatial grid, which is inspired by the physical a priori knowledge that atoms in a crystalline solid tend to form regular lattices. Although this constraint has proven to be powerful for solving this very under-determined inverse problem in many cases, its key limitation is that, in practice, defects may occur that cause atoms to deviate from regular lattice p","authors_text":"Felix Lucka, Hermen Jan Hupkes, Kees Joost Batenburg, Poulami Somanya Ganguly","cross_cats":["cond-mat.mtrl-sci","cs.NA","eess.IV","physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2020-02-03T13:24:21Z","title":"Atomic Super-Resolution Tomography"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2002.00710","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":"sha256:7f87b37823a7d5293b8fbca293104ea769d40179bf9fd6e45dcd293cb5a1ba1f","target":"record","created_at":"2026-07-05T01:18:17Z","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":"76a9d40f755dc2ced74426e89cb17d24aff3db16f553011ba1168a8b8bbcde63","cross_cats_sorted":["cond-mat.mtrl-sci","cs.NA","eess.IV","physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.NA","submitted_at":"2020-02-03T13:24:21Z","title_canon_sha256":"728c857c4da2988460de32b8212277328302fe5817179181a46d2dbfd3d54130"},"schema_version":"1.0","source":{"id":"2002.00710","kind":"arxiv","version":2}},"canonical_sha256":"1af696a935f19fd17596c2cf42dfe9943ee522504c234503738cb35b0c354085","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1af696a935f19fd17596c2cf42dfe9943ee522504c234503738cb35b0c354085","first_computed_at":"2026-07-05T01:18:17.576404Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:18:17.576404Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XHhJTGzzWtXCoS5Oz2Brcf8bhYApg9RHoCi9AAvQh9HPDU+m95el7/5F1hn+BEhJ0m3+nLucnUEoVukVCV5tBA==","signature_status":"signed_v1","signed_at":"2026-07-05T01:18:17.576884Z","signed_message":"canonical_sha256_bytes"},"source_id":"2002.00710","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7f87b37823a7d5293b8fbca293104ea769d40179bf9fd6e45dcd293cb5a1ba1f","sha256:c750e703778121bcd894e5fcc3c380ae8809cad77db14089a82497690453227b"],"state_sha256":"47c755a0dd3c89aaa65e869f25fc1fdfaa1af4dccb523d301ff99a41a32e371a"}
