The application of semi-local coordinates in this context allows the generation of PESs in a very cost-efficient way. For this, we employ the recently introduced flexible adaptation of local coordinates of nuclei (FALCON) coordinates. By introducing an additional transformation step, concerning only a fraction of the vibrational degrees of freedom, we can achieve linear scaling of the accumulated ","authors_text":"Carolin K\\\"onig, Ove Christiansen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2016-05-05T18:03:56Z","title":"Linear-scaling generation of potential energy surfaces using a double incremental expansion"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1605.01674","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":"sha256:126e4513af1c14796b6210da48a5c5a510f6006aaed7328776d0426d23041851","target":"record","created_at":"2026-05-18T01:09:11Z","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":"239438da4ad9c07a3ff6b07398ad4528f550e237e318f248e5cebef460fa0648","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2016-05-05T18:03:56Z","title_canon_sha256":"0c18b9f6468eb572383aac7c9612f23ba5ad6d94e99d6d17d7966de6722795d6"},"schema_version":"1.0","source":{"id":"1605.01674","kind":"arxiv","version":2}},"canonical_sha256":"c93355c7de6607405b8b6306a75ad7e4e5e48ef0609a5d6ad3e61895486615a8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c93355c7de6607405b8b6306a75ad7e4e5e48ef0609a5d6ad3e61895486615a8","first_computed_at":"2026-05-18T01:09:11.685628Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:09:11.685628Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Hx2amuI939xeW1Kn0R22+PxFXUBkebY/OLgjn2Z3OQqKQFRnAZu+LkYA9xv6NeY8VqtCKICsWbjyQ8QfkkSyDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:09:11.686211Z","signed_message":"canonical_sha256_bytes"},"source_id":"1605.01674","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:126e4513af1c14796b6210da48a5c5a510f6006aaed7328776d0426d23041851","sha256:e7c09895f1bc2387c25dfae5ee05c9dd131dc54e5b50c79dc2e1c7091ebc84f9"],"state_sha256":"d29b7442b54fd221e504ebca3d4f23864d6b2b7cdd49db009dfdd42acd28cf73"}
