We find that if the width of the channel is a (small) integer multiple of the sphere's diameter, the spheres self-organize into two-dimensional layers that slide on each other and the suspension's effective viscosity is significantly reduced. Each two-dimensional layer is found to be structurally liquid-like but their dynamics is frozen in time.","authors_text":"Cyan Umbert Lopez, Dhrubaditya Mitra, Francesco Picano, Luca Brandt, Pinaki Chaudhuri, Walter Fornari","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2015-06-29T16:37:29Z","title":"Rheology of confined non-Brownian suspensions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1506.08722","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:b3ba5e1854f40ebe90176bc6510b796d91de70146714c3145f3ae56cf0e78041","target":"record","created_at":"2026-05-18T01:22:58Z","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":"e9ce0f8305b639d6b7af066448e136cb82733b4597983b209fa99e1d0ac80312","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2015-06-29T16:37:29Z","title_canon_sha256":"8cbedf65b88aee79f4dcb38ff6e0f7b697de72a8df360d0ec6068f111701f502"},"schema_version":"1.0","source":{"id":"1506.08722","kind":"arxiv","version":1}},"canonical_sha256":"bd0dc3470130fc019b6dd1f09796ef86e8c1022fee9a6f014ed62117110511de","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bd0dc3470130fc019b6dd1f09796ef86e8c1022fee9a6f014ed62117110511de","first_computed_at":"2026-05-18T01:22:58.485403Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:22:58.485403Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VEMnaDGwvZ4Z/9eob6t0EafvUH1lcWBFzs7b63kPTkKhnd7eRJ8kUUHlqxvyWnReGEvlfF6SJ4ib4PTqy9akAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:22:58.485993Z","signed_message":"canonical_sha256_bytes"},"source_id":"1506.08722","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b3ba5e1854f40ebe90176bc6510b796d91de70146714c3145f3ae56cf0e78041","sha256:2e648df90c7bb370ba158809b58a56e49a41f85e8ccc498c7bf9578be0ee17fb"],"state_sha256":"dfff107623bd8a659bb9c07a1b6312423ea790e8ddfe062a585eb5f60fe2a6d6"}
