Chem. Phys. 143, 102815, (2015)]. In this method both the zeroth order and first order wavefunctions are sampled stochastically by propagating simultaneously two populations of signed walkers. The sampling of the zeroth order wavefunction follows a set of stochastic processes identical to the one used in the FCIQMC method. To sample the first order wavefunction, the usual FCIQMC algorithm is augmented with a source term that spawns walkers in the sample","authors_text":"Ali Alavi, Guillaume Jeanmairet, Sandeep Sharma","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2016-11-08T13:26:14Z","title":"Stochastic multi-reference perturbation theory with application to linearized coupled cluster method"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.02511","kind":"arxiv","version":1},"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:d6ebfffd5ec04850b18da4cd9b18a36ff24c5ef3b185e9052d5acbf93c1d751a","target":"record","created_at":"2026-05-18T00:49:23Z","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":"8f1b3524f48222c686f50bd8609376f54ee1f85905058ad95cd6422278ea098f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2016-11-08T13:26:14Z","title_canon_sha256":"9a592c8579be2343faeb5f48975e218fd395a402b9eb9717dd5741abbb135c5d"},"schema_version":"1.0","source":{"id":"1611.02511","kind":"arxiv","version":1}},"canonical_sha256":"9a344ea35c67de52ce2ec239d1d9f8fd0ba25ff9123a474841ce6c701769b0cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a344ea35c67de52ce2ec239d1d9f8fd0ba25ff9123a474841ce6c701769b0cc","first_computed_at":"2026-05-18T00:49:23.387604Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:49:23.387604Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eLXCh1zyeZ+bQhd1QZ8sxRzo2WYVZgbEMcHsGSZ1gSB+pXah+gKz9Rqw2rReVc4EkttTzxYAstt/9V1s3bDeCw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:49:23.388307Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.02511","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d6ebfffd5ec04850b18da4cd9b18a36ff24c5ef3b185e9052d5acbf93c1d751a","sha256:0c58f27b4c26c5c4cef8efb6debbf9e21417be94bb8f13b1256053d9afc53656"],"state_sha256":"5814995ae0bf141348491cd9fdcdc91a8347fec92d7fc47d64f8c836fb4b5f04"}
