This approximation scheme can be seen as a simple improvement of the local potential approximation (LPA) where the derivative terms in the effective action are promoted to arbitrary momentum-dependent functions. As in the LPA the only field dependence comes from the effective potential, which allows us to solve the renormalization-group equations at a relatively modest numerical cost (as compared, e.g., to the Blaizot--Mend\\'ez-Galain--Wschebor approx","authors_text":"F\\'elix Rose, Nicolas Dupuis","cross_cats":["cond-mat.quant-gas","cond-mat.str-el","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2018-01-09T19:30:00Z","title":"Nonperturbative renormalization-group approach preserving the momentum dependence of correlation functions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1801.03118","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":"sha256:456409b4a8cd4ac06dd57be52d5c53db6ed38712d884f2926a27d3f610ed61aa","target":"record","created_at":"2026-05-18T00:15:09Z","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":"db810d3144c5b0420d957a80a3565fe1ba4ed46f031f0815ca557531e90fc736","cross_cats_sorted":["cond-mat.quant-gas","cond-mat.str-el","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2018-01-09T19:30:00Z","title_canon_sha256":"015f406cfe96a5fc9b34670eee1c9d44b0fe86187668269c0a20b024c04715f2"},"schema_version":"1.0","source":{"id":"1801.03118","kind":"arxiv","version":2}},"canonical_sha256":"dd93441fe4386e6f9d523eff660a4f7dcfa1243cb1f61eeda8bc79037b1a37ba","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dd93441fe4386e6f9d523eff660a4f7dcfa1243cb1f61eeda8bc79037b1a37ba","first_computed_at":"2026-05-18T00:15:09.849386Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:09.849386Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Rd4exLCAlOFgZN3bzx9CAekr4zqYZLBW/J9S13MuT3Dk4qa84qRtLFDdwdwoKHtoUPZ2DkjsSHhTB0Gvr11sDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:09.849886Z","signed_message":"canonical_sha256_bytes"},"source_id":"1801.03118","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:456409b4a8cd4ac06dd57be52d5c53db6ed38712d884f2926a27d3f610ed61aa","sha256:7d149e9682c1271d338400c6392192f152a9519f0430db5506057855dd678590"],"state_sha256":"e8dd9c4e858b5c7b9b26ea1beaa8b2b2f1833bc4598b80e839d346c9e6de6160"}
