For small coupling constant we prove return to equilibrium exponentially fast in time. The novelty in this context is to model the particle by a harmonic or anharmonic oscillator, respectively. The proof is based on explicit formulas for the time evolution of Weyl operators in the harmonic oscillator case. In the anharmonic oscillator case, a Dyson's expansion for the dynamics is essential. Moreover, we show in the harmonic oscillator case, that $\\R$ is the absolute cont","authors_text":"Martin K\\\"onenberg","cross_cats":["math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math-ph","submitted_at":"2011-01-06T10:50:36Z","title":"Return to Equilibrium for an Anharmonic Oscillator coupled to a Heat Bath"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1101.1188","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":"sha256:1780348052184e68e61bfb12b311703ad069eac7ac187fe6294aba984e38c988","target":"record","created_at":"2026-05-18T02:04:12Z","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":"44c34cf43a77a102a7b91ab5644f9678522e333fcae854ccf9336ffc3fc8870d","cross_cats_sorted":["math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math-ph","submitted_at":"2011-01-06T10:50:36Z","title_canon_sha256":"e5d9421126dc110258dcf3cba8f407a6ef44a041bcf30681682835e704a72bf3"},"schema_version":"1.0","source":{"id":"1101.1188","kind":"arxiv","version":1}},"canonical_sha256":"f3ac2fc7f0bf549ae90cba147086d6a811b028e42a6c7e64eab62d499b71660a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f3ac2fc7f0bf549ae90cba147086d6a811b028e42a6c7e64eab62d499b71660a","first_computed_at":"2026-05-18T02:04:12.352176Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:04:12.352176Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xzool+7lcbQHsugVr/8TkrCyV8BZjGVbfILmlc3EFlv784IuQrWqTNbTLjQFcaHny5cjOVKzSbsTjHx4cqy/DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:04:12.352842Z","signed_message":"canonical_sha256_bytes"},"source_id":"1101.1188","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1780348052184e68e61bfb12b311703ad069eac7ac187fe6294aba984e38c988","sha256:b540d18e6089c9888697ee8758043c60e1e1e8e223c5db986e46adc053cc2c3b"],"state_sha256":"81937e62460fe88fe1428e40f424401ae64b5e3d8422518c1cd87b59febbb002"}
