Here we collect some findings for the quartic model, and for U(1) and SU(2) models in the presence of a determinant, which have some features not discussed before, due to a singular drift. We find evidence for a relation between classical runaways and stable thimbles, and give an example of a degenerate fixed point. We typically find that the distributions sampled in complex Lang","authors_text":"Denes Sexty, Erhard Seiler, Gert Aarts, Lorenzo Bongiovanni","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2014-07-08T14:05:02Z","title":"Some remarks on Lefschetz thimbles and complex Langevin dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1407.2090","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:e9d558c6dc67a8fd38501a6ce3f41a7b2b9fff148b613753234d8c49e471ce7e","target":"record","created_at":"2026-05-18T01:42:40Z","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":"64320368b68e140c855d6732df0403a719947b07fddede323dc913552be62324","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2014-07-08T14:05:02Z","title_canon_sha256":"79517ac759a28f3ccc30d4cc1e2e705a50ed066691eeae95b41c7a4c9ceecb89"},"schema_version":"1.0","source":{"id":"1407.2090","kind":"arxiv","version":2}},"canonical_sha256":"da14104b959b355ca6739cb8d1ff63155b51a2ec1a601c70e1a4233c66c08341","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"da14104b959b355ca6739cb8d1ff63155b51a2ec1a601c70e1a4233c66c08341","first_computed_at":"2026-05-18T01:42:40.923677Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:42:40.923677Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oSYDOIDs1P7qPF/fBvv4iFHPQmC5NqHuGjAhe5mY31cL+XG4/yLbuVF3Z30Npgl67Uuf+GDGIt1JSefgpy41CQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:42:40.924248Z","signed_message":"canonical_sha256_bytes"},"source_id":"1407.2090","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9d558c6dc67a8fd38501a6ce3f41a7b2b9fff148b613753234d8c49e471ce7e","sha256:75ab20db3a7af3eb40b1fac15ecb6282e36de0e8bc54dfa2f65722612a74ce96"],"state_sha256":"3283257e72df1e8508abec9f30e11d0462b4772aa4be432aa6a29a60fbe7bee1"}
