Using machine-learning potential-based molecular dynamics with the MACEField model, we systematically vary supercell size to reveal a clear transition from homogeneous polarization switching to domain-wall-mediated switching, accompanied by a coercive field increase of over 50%. Shannon entropy analysis demonstrates that this transition is driven by size-dependent polarization fluctuations that promote 180 ","authors_text":"Po-Yen Chen, Teruyasu Mizoguchi","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-05-25T06:40:13Z","title":"Transition from Homogeneous to Domain-Wall-Mediated Polarization Switching in BaTiO3: A Machine-Learning Molecular Dynamics Study"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.25485","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:a97800c44ffca7fffbd82c6354b0c6e76a7f09be35d99f3663bf47e6eede50c9","target":"record","created_at":"2026-05-26T02:04:38Z","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":"a533a62026b92e14a630507140e399b961101d12e7a580ea8b21d1f4524e8fdd","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-05-25T06:40:13Z","title_canon_sha256":"469985e86cbee6bf500297795392c8f7bc0822f74ee95bb0d86eceb043d50560"},"schema_version":"1.0","source":{"id":"2605.25485","kind":"arxiv","version":1}},"canonical_sha256":"6605e2c58010aa67bbc5d36b4b8358e479d0f8d7fe7911c59759e604fa4578cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6605e2c58010aa67bbc5d36b4b8358e479d0f8d7fe7911c59759e604fa4578cc","first_computed_at":"2026-05-26T02:04:38.696005Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-26T02:04:38.696005Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HH0PObptdgYDLfXqMGvBIaH7oJJ0Dv66cDLvRzJlaqdSqu7lSS1Plv/JTSsI7RdH1T2GDhQxvS0rLZlET5Q+Aw==","signature_status":"signed_v1","signed_at":"2026-05-26T02:04:38.696660Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.25485","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a97800c44ffca7fffbd82c6354b0c6e76a7f09be35d99f3663bf47e6eede50c9","sha256:e5c072135b7ab990fdb6b7b37fb12ee6b2785fe43dc47327b798659df4a60c8c"],"state_sha256":"99bef7ab90ba821c456fd4213fd9e4e6525a68857355e8f8c4a746a2affaae2b"}
