We first address the solution of a complex 0-dimensional phi^4 theory. Although very simple, this toy-model makes us appreciate a few key issues of the method. In particular, we will solve the model by a correct accounting of all the thimbles giving a contribution to the partition function and we will discuss a number of algorithmic solutions to simulate this (simple) model. We will then move to a chiral random matrix (CRM) theory. This is a somehow more realistic setting, giving us once again the c","authors_text":"Francesco Di Renzo, Giovanni Eruzzi","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2015-07-14T14:19:13Z","title":"Thimble regularization at work: from toy models to chiral random matrix theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1507.03858","kind":"arxiv","version":3},"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":"sha256:58fba55d0497a2a4af3e3812a99235fa6b3796f09701028b172614cc8225ea71","target":"record","created_at":"2026-05-18T01:28:53Z","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":"512d6eb19480c90891703f72cb442b9efdecf10a098547294e70be53b5fa75e2","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2015-07-14T14:19:13Z","title_canon_sha256":"0a283f8aa27b351f547ea918eb60107d55c5284201b9971b238cc6fd65fb0810"},"schema_version":"1.0","source":{"id":"1507.03858","kind":"arxiv","version":3}},"canonical_sha256":"6baa376be761771cd3265eb46e80b85c85342b366cf9ad012907aad72a8f3581","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6baa376be761771cd3265eb46e80b85c85342b366cf9ad012907aad72a8f3581","first_computed_at":"2026-05-18T01:28:53.784449Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:28:53.784449Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZvR4OIU29YWMhumq9RIWr66laeSc/jCc5/WHrTkZddb5EViMU14X9B7Y7WJHotVEmtbsnV7o9SJvFAKxwKxgDg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:28:53.785182Z","signed_message":"canonical_sha256_bytes"},"source_id":"1507.03858","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:58fba55d0497a2a4af3e3812a99235fa6b3796f09701028b172614cc8225ea71","sha256:0a5b35abb9cde0a2c29f0b6b82de2efdddd9d77d0c9c98f0ddacb9d49ed007ea"],"state_sha256":"d6506a8c60d47c5a026e5a61b642aabbf72c61df3954468fbad4b14189041c41"}
