Focusing on systems in classes BDI and D, we find crossings in single-particle entanglement spectra for quantum quenches between different symmetry-protected topological phases. The entanglement-spectrum crossings are shown to be stable against symmetry-preserving disorder and faithfully reflect both $\\mathbb{Z}$ (class BDI) and $\\mathbb{Z}_2$ (class","authors_text":"Masahito Ueda, Zongping Gong","cross_cats":["cond-mat.quant-gas","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2017-10-15T06:53:47Z","title":"Topological Entanglement-Spectrum Crossing in Quench Dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.05289","kind":"arxiv","version":4},"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:c222c847a4b843e4517ffddefb8cfb1c800b74988afa116d48a89419244b78da","target":"record","created_at":"2026-05-17T23:57:59Z","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":"2383f2df43e0ba7d86f267d7d64e6e86380f7c40ccea0349b4a42f4ec16997c8","cross_cats_sorted":["cond-mat.quant-gas","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2017-10-15T06:53:47Z","title_canon_sha256":"08daaf3b798abc6e87461efa6bcbd726635f58741d04c61ee20771181a09d115"},"schema_version":"1.0","source":{"id":"1710.05289","kind":"arxiv","version":4}},"canonical_sha256":"eabbc796553c574ac97bccf5842debe5ee4d6490b97da3ae8ba1a8731b6af9a9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eabbc796553c574ac97bccf5842debe5ee4d6490b97da3ae8ba1a8731b6af9a9","first_computed_at":"2026-05-17T23:57:59.735008Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:57:59.735008Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gz0TEXLgmUlikOpehQ649S9wHZixZFENd0zN/0QccMWD0zmQhB4AAwJomItgry4cQzRywnacbUmW0AyiOxEEBw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:57:59.735656Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.05289","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c222c847a4b843e4517ffddefb8cfb1c800b74988afa116d48a89419244b78da","sha256:8d922a1aed780b37da3b63455f82fde928963e20bd63eaf9c10022df009e8587"],"state_sha256":"bf5e5729ab1b8f589c20f484559ceda6edda127c65663ef6164df1b06e49d4c9"}
