By numerically studying the participation ratio, we identify a sharp crossover between different phases at a disorder strength close to the disorder strength at which subdiffusive behaviour sets in, significantly below the many-body localization transition. We repeat the analysis in the conventionally used computational basis, and show that many-body localized eigenstates are much stronger localized in the Fock basis constructed out of the natural orbitals than ","authors_text":"Vadim Cheianov, Vladimir Gritsev, Wouter Buijsman","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.dis-nn","submitted_at":"2017-12-19T12:15:02Z","title":"Many-body localization in the Fock space of natural orbitals"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.06892","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":"sha256:486d437b2038b5e4c6f0f3f37abcf031de5b59166b25f090bacd8e6e13bfd2b4","target":"record","created_at":"2026-05-18T00:12:24Z","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":"58d14fcc692d1e8916bf390b5bb2740a9819747c21afee673e164b87120e3cdf","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.dis-nn","submitted_at":"2017-12-19T12:15:02Z","title_canon_sha256":"f1981c32844f64ad05fcb783b20cbe572af37aef87b5edc8e2e5d413b3f2e12d"},"schema_version":"1.0","source":{"id":"1712.06892","kind":"arxiv","version":3}},"canonical_sha256":"da0c62d3060355153e301fb1371a1588b954c17eab2acf466f123403b8ac72db","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"da0c62d3060355153e301fb1371a1588b954c17eab2acf466f123403b8ac72db","first_computed_at":"2026-05-18T00:12:24.663866Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:12:24.663866Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JU5BAI8kQeaeTnZf+76d7dOIUvd02n8Iaqo6wqFx8YGUIA6gsZaPlnV/rKSmXdnbc9cpfKK0Id04KTHH+VvNBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:12:24.664491Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.06892","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:486d437b2038b5e4c6f0f3f37abcf031de5b59166b25f090bacd8e6e13bfd2b4","sha256:bf29c8b526c7f7202f05523162f8505d5adcde551e13626478d8faaaed9fb2eb"],"state_sha256":"a5eaea303a46ab8dabda8f5bfa437425f0109b7c2941dd05f6e118a40da3f445"}
