The shear viscosity decreases as we tune the interaction strength 1/ak_F from the Bardeen-Cooper-Schrieffer side of the Feshbach resonance towards Bose-Einstein condensation limit and it acquires the smallest value for 1/ak_F approx 0.4, with a minimum value of (eta/s)_min approx 0.2 hbar/k_B, which is about twice as small as ","authors_text":"Aurel Bulgac, Gabriel Wlaz{\\l}owski, Wei Quan","cross_cats":["hep-lat","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2015-04-10T06:39:53Z","title":"Perfect-fluid behavior of a dilute Fermi gas near unitary"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1504.02560","kind":"arxiv","version":3},"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:a00e98e833fa09c5a378ea9c2bfe53ead5e4031004b3457fc20f843280ea648d","target":"record","created_at":"2026-05-18T01:09:47Z","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":"5365aa1a3bf0ca93a860edd5b6f304df1a4b932663f54666f0f41b797fd2b262","cross_cats_sorted":["hep-lat","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2015-04-10T06:39:53Z","title_canon_sha256":"f4b7d1c352c33f0da0281cd55b1f7c0eeeacf11555ec57216d5dc410bbc47b7a"},"schema_version":"1.0","source":{"id":"1504.02560","kind":"arxiv","version":3}},"canonical_sha256":"d1dfdb09b4df280af807908731af1204ae75c4d87174aa2cc2f69e657bf402bf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d1dfdb09b4df280af807908731af1204ae75c4d87174aa2cc2f69e657bf402bf","first_computed_at":"2026-05-18T01:09:47.214402Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:09:47.214402Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Rg0ziUrSGPCW+QN/2xsQ0/IL9JfeR9xDMizJqO4YuikqTievWGYGWkaTErICAK2cDzR2rpgMZiIqf2MZnG7CDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:09:47.215087Z","signed_message":"canonical_sha256_bytes"},"source_id":"1504.02560","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a00e98e833fa09c5a378ea9c2bfe53ead5e4031004b3457fc20f843280ea648d","sha256:c3dade0f46e78771fd12acad35dbd1c0fc6c8e2644b75a71fc00d84ed1706336"],"state_sha256":"6264eae7a844fef72b0776780e513d0330db813ced5cdc90b7123cabe5aec101"}
