We also propose that the gauge-fixed local Berry connection can be an- other effective tool to estimate precisely the quantum critical point. For a demonstration, we calculate the gauge-fixed Berry connection and the local Z2 Berry phase of the antiferromagnetic Heisenberg model on a staggered bond-alternating ladder, and estimated quantum critical point is consistent with other methods.","authors_text":"Synge Todo, Yuichi Motoyama","cross_cats":["physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2013-10-01T09:25:55Z","title":"Path-integral Monte Carlo for the Gauge-fixed Berry Connection and the Local Z_2 Berry Phase"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1310.0205","kind":"arxiv","version":1},"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":"sha256:842ef5d4c047ce36779b472381c5ef9b5a2fcbacd50b13e24a8b1b2742214457","target":"record","created_at":"2026-05-18T03:11:45Z","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":"ad15d717a3b732a2b884e9e4b99c586fd67696b6ae549c0aa535b261a4b55efd","cross_cats_sorted":["physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2013-10-01T09:25:55Z","title_canon_sha256":"d885a1639e52d324ea9283c98999f81c537a51cd016c1339e0f2e28296c88585"},"schema_version":"1.0","source":{"id":"1310.0205","kind":"arxiv","version":1}},"canonical_sha256":"95db807fd544727b5cfb7e5fb558b3323448ac25d9815b58f58552c713e42292","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95db807fd544727b5cfb7e5fb558b3323448ac25d9815b58f58552c713e42292","first_computed_at":"2026-05-18T03:11:45.168617Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:11:45.168617Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Jc04FBLBcs2HsPh2bZ8pjKTbXbeFkY+tW99B4lZlID8yW6p3oVxA6V2po/AoegMmF4KYnLbRgK6ggFzARIN6DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:11:45.169215Z","signed_message":"canonical_sha256_bytes"},"source_id":"1310.0205","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:842ef5d4c047ce36779b472381c5ef9b5a2fcbacd50b13e24a8b1b2742214457","sha256:09847070b08ee92aa963c3833c1a8c8711d678b20f54e325882f1fb7a3d13a58"],"state_sha256":"bb0abc2ed684d36b54806ce47553a062dd70acb6ee3730865be9dae30d055445"}
