For this purpose we consider a finite-size scaling (FSS) framework. Our working hypothesis is based on a scaling assumption of the fidelity in terms of the FSS variables associated to $\\lambda$ and to its variation $\\delta \\lambda$. This framework entails the FSS predictions for continuous transitions, and meanwhile enables to extend them to first-order transitions, where the FS","authors_text":"Davide Rossini, Ettore Vicari","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2018-07-04T16:50:21Z","title":"Ground-state fidelity at first-order quantum transitions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.01674","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:b1e5148844a9071a9d492ac2473d14a2911a034f2d0147326f2c4820b7160269","target":"record","created_at":"2026-05-17T23:57:31Z","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":"5ce4b7fcbfcc99d9cc21f56faeed23ee690331e0a7ccd66f78d5ab3eed4ac306","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2018-07-04T16:50:21Z","title_canon_sha256":"8f6c3ce36780cdd3c2f58caa0ecb963f6f659d0bc2baf31a2136c8cde172dea7"},"schema_version":"1.0","source":{"id":"1807.01674","kind":"arxiv","version":2}},"canonical_sha256":"6d863d88d094958fd019792a9d5c7be6bee3a91ea640252944f1a1a92b8bd759","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6d863d88d094958fd019792a9d5c7be6bee3a91ea640252944f1a1a92b8bd759","first_computed_at":"2026-05-17T23:57:31.704795Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:31.704795Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qkrsXbD9RNm4AB/U0WgtUisCZWcBB78OxDoONlnjuwlzGZU+Aahdkoau3OVqkGvcxcq50CGHMZdAGWdom47CDA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:31.705254Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.01674","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b1e5148844a9071a9d492ac2473d14a2911a034f2d0147326f2c4820b7160269","sha256:205b7847fc9081d5e92951749955ee4e7502f23425d4cfe596c348f656d7d960"],"state_sha256":"00820c20afc98b6620b0a4d365b481fe5e75d8de3cc29cb25811f4582cebdbca"}
