Two different methods are applied and compared for this problem. One is a perturbation method based on a unitary transformation. With the merit of our unitary transformation, non-adiabatic effect can be taken into account efficiently. And the other one is the numerically exact method, namely the quasi-adiabatic path-integral (QUAPI) propagator technique. We find that the analytical method works well for a wide parameter range and show good a","authors_text":"Hang Zheng, Keiichiro Nasu, Peihao Huang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-11T10:47:38Z","title":"The dynamics of a qubit in a spin-boson environment: a comparison between analytical and numerical method"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.2609","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":"sha256:6ed66894b166bdbe2ede19d9fd3d941ccb95a35deefef0e3507b2740496540cd","target":"record","created_at":"2026-05-18T04:36:09Z","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":"bd51e1b7e3485816eed1bd7915b3a4c478e971a0efa7c91d167fb3d18aa2f398","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-11-11T10:47:38Z","title_canon_sha256":"d3d6ad299d2c9a3277567c7b787bfe957dcb61a9fc3b122d084a25487bd594cf"},"schema_version":"1.0","source":{"id":"1011.2609","kind":"arxiv","version":1}},"canonical_sha256":"0ce2a4e370a748c69241b448cbac7a81de2176739945388d290cf2b548450e23","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0ce2a4e370a748c69241b448cbac7a81de2176739945388d290cf2b548450e23","first_computed_at":"2026-05-18T04:36:09.902713Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:36:09.902713Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6ZoHmLV8Boq52kxW5EWH6ZmOXsaLISoGRRVWgRyG97o6hSo7BtA5I3809G4KnuPYCNcPVEzXqviUvqj7l2DTBg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:36:09.903358Z","signed_message":"canonical_sha256_bytes"},"source_id":"1011.2609","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6ed66894b166bdbe2ede19d9fd3d941ccb95a35deefef0e3507b2740496540cd","sha256:8a8e3c7581bddee05535a74762ad6b0dabd8fb4858323980503431ab0c174ab4"],"state_sha256":"802640e65173967a098195026fb8733099c693f7ac752fa93c8894efcf54e62b"}
