The speed of sound in the non-relativistic plasma turns out to be $\\sqrt{3}$, which clearly violates the conjectured upper bound. We identify this as a natural consequence of the Lorentz symmetry breakdown at $ z=3 $ Lifshitz fixed point. In our analysis, we compute bulk viscosity to entropy ratio for quantum field theory dual to Lifshitz gravity in $ 2+1$ dimensions and it turns out that for this particular holographic model this ratio is abov","authors_text":"Arpan Bhattacharyya, Dibakar Roychowdhury","cross_cats":["cond-mat.str-el"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-03-11T10:07:29Z","title":"Holographic Lifshitz fluids in 1+1 dimensions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1503.03254","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":"sha256:86390d672cf22576d6ecfb30701789814aba1ef9be74ba05475eba9cad1ab07e","target":"record","created_at":"2026-05-18T00:25:02Z","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":"6ce91225a1105738347011ff354c69b97956d254a30165e9bf36aa725cf83a8b","cross_cats_sorted":["cond-mat.str-el"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-03-11T10:07:29Z","title_canon_sha256":"0803fe6133c1fd8bd20b2aa19bdbb669a7ca540ab52b76f0c9c58a06557f468c"},"schema_version":"1.0","source":{"id":"1503.03254","kind":"arxiv","version":2}},"canonical_sha256":"5191dc1bc4581f59f4716f53c512c089d8556df7f2a954c0d2b06dc7dc84595b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5191dc1bc4581f59f4716f53c512c089d8556df7f2a954c0d2b06dc7dc84595b","first_computed_at":"2026-05-18T00:25:02.461942Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:25:02.461942Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uBD8pSR/76PCCjrP3/Uao6CKvlcXTTlBr4yACjF8eOLocYzWSgTRP1jIskkQZXEIV7p/cLmB/D7i0TV4DRrJCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:25:02.462383Z","signed_message":"canonical_sha256_bytes"},"source_id":"1503.03254","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:86390d672cf22576d6ecfb30701789814aba1ef9be74ba05475eba9cad1ab07e","sha256:3889c848c2c0d7eb376bc84dd76c735f6599041bacf3f980e0b16f661433f309"],"state_sha256":"eef75cce1e1a2ebc41939ab8420f1abbae9279d964f595e155e746624e0f96b2"}
