We find that phase averaging is the dominant decoherence effect, rather than information exchange between tracer and gas particles. While a coherent superposition of two wave packets with different mean positions quickly turns into a mixed state, it is demonstrated that such superpositions of different momenta are robust to phase averaging, until the two wave packets acquire a different position due to the different velocity of each wave packet.","authors_text":"Ingo Kamleitner","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-23T09:19:46Z","title":"Collisional decoherence of a tracer particle moving in one dimension"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.4080","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:f79edbec53b0b8030e076e3f03242c9c0fd8a00ccbec7f74be6b923ca2d72eec","target":"record","created_at":"2026-05-18T04:25:13Z","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":"60ebe9084ee379b64ab6acd7e326b7bac65ce2220b66062e6441d9eff0d98214","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-23T09:19:46Z","title_canon_sha256":"2cb66214be56e09908b62fd40759fa671496c069c71f2efc3a9af7c43079d878"},"schema_version":"1.0","source":{"id":"1007.4080","kind":"arxiv","version":2}},"canonical_sha256":"13ff22827d3324b457bc48698240bd37d7b69b3244c0a56871f6ea75260c9ae6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"13ff22827d3324b457bc48698240bd37d7b69b3244c0a56871f6ea75260c9ae6","first_computed_at":"2026-05-18T04:25:13.155189Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:25:13.155189Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ldrzaGM8Rzw027VcPcUR2fvyQEARlHFSQeuHMB7crfotQPM/ylJhU/yda4dTqb88DgR0FkoocJwFyhhxh+2CDg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:25:13.155863Z","signed_message":"canonical_sha256_bytes"},"source_id":"1007.4080","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f79edbec53b0b8030e076e3f03242c9c0fd8a00ccbec7f74be6b923ca2d72eec","sha256:8c4f4009d0fa14d5e6b8f6e4d19d104697ed9573af8e84e4a61af50212e265cd"],"state_sha256":"e8033571bc3676a9ac6d594892a681d5f3b4f6fd72a794746538c4e882ab14c3"}
