We show here how these superpositions can become indistinguishable from a classical mixture by the interaction with fermions. We calculate the reduced density matrix for a locally rotationally symmetric Bianchi I model and show that the purity factor for the triads decreases by decoherence. In this way, the universe assumes a definite orientation.","authors_text":"Christian Schell, Claus Kiefer","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-10-01T14:26:31Z","title":"Interpretation of the triad orientations in loop quantum cosmology"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1210.0418","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:ddcdc145b7fc0fc6d69cb3f057f53ecb0956ae756152edda0af625e186168212","target":"record","created_at":"2026-05-18T03:35:53Z","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":"f18040af87ea65ca3c5045246586b20f5ca25d24004567dd1571d9d6b53de203","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-10-01T14:26:31Z","title_canon_sha256":"49b7473b3d852d80ac366161d81c06d1226e5d9da75f153a5e7d09e22125f318"},"schema_version":"1.0","source":{"id":"1210.0418","kind":"arxiv","version":2}},"canonical_sha256":"c3ad18ea037bcf70e14b6c3ceb2cadfac2e812830f5ef6808b4aa5483506fe5d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c3ad18ea037bcf70e14b6c3ceb2cadfac2e812830f5ef6808b4aa5483506fe5d","first_computed_at":"2026-05-18T03:35:53.855688Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:35:53.855688Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hfjYzBZa+85XT+7TFzpOhYD8PI7rl5/4EHPiLJSfrUBMQSiMyi5Rga4iOI4Bu7tUSPuHN3dqUdSMfIZQR4p+AA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:35:53.856543Z","signed_message":"canonical_sha256_bytes"},"source_id":"1210.0418","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ddcdc145b7fc0fc6d69cb3f057f53ecb0956ae756152edda0af625e186168212","sha256:1024654b21662ab84a81465b46530cd34a2d2985ddff081ce5a74fb71fdf7b91"],"state_sha256":"e7bbe08a30f6a7efdd2b0ca46debf70bf127e32f35eddfc2cf155f2b938ad9ff"}
