To assess the range of validity of the method in a systematic way, we consider the SU($N$) Hubbard model with the fermion degeneracy $N$ as a natural semiclassical expansion parameter. Using both a numerical and a perturbative analytical approach we show that fTWA is exact at least up to and including the prethermalization dynamics. We discuss the limitations of the method beyond this regime.","authors_text":"Alexander Osterkorn, Stefan Kehrein","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2020-07-09T20:59:49Z","title":"Systematic large flavor fTWA approach to interaction quenches in the Hubbard model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2007.05063","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":"sha256:18c0ff550462f35d9ffd9f33a15a0ea334887d1034cad3aea1bc40e53ce6f762","target":"record","created_at":"2026-07-05T08:59:47Z","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":"6a6634544756e32c35524fcfdb277600105102d1f2f1b1b73054ef36aec23801","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2020-07-09T20:59:49Z","title_canon_sha256":"9108d3cf2b3e4e9497a1cc6cc8408b0c54ee4ebbed1956c1a7c0bbdc1a87617b"},"schema_version":"1.0","source":{"id":"2007.05063","kind":"arxiv","version":2}},"canonical_sha256":"2fe84b652dfcf1477fc3d8bf7ccda262040344d008089bd949137f6cc4b36e5c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2fe84b652dfcf1477fc3d8bf7ccda262040344d008089bd949137f6cc4b36e5c","first_computed_at":"2026-07-05T08:59:47.941700Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:59:47.941700Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lqLSFFJKQmr1htlOSw0ooeb/aVzqK/Wyz4wXRELH6u0atDg/CrcM3fBX/wPR4luNy7ZWnftYaf83g2uZDxd0Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:59:47.942122Z","signed_message":"canonical_sha256_bytes"},"source_id":"2007.05063","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:18c0ff550462f35d9ffd9f33a15a0ea334887d1034cad3aea1bc40e53ce6f762","sha256:b9485b614d6f0e6406670f7b9dac87a72f273e40e66ce79d54c21a2e2ba256dd"],"state_sha256":"4f72bfd03df5cc0451a2ea8e90cf2715bde01c5318959e67600708a636912124"}
