Without HD this system describes irrotational dust - Dark Matter (DM) as we see it on cosmologically large scales. DM particles correspond to the shift-charges - Noether charges of the shifts in the field space. Higher derivative corrections usually describe a deviation from the thermodynamical equilibrium in the relativistic hydrodynamics. Thus we show that mimetic matter with HD corresponds to an imperfect DM which: i) renormalises the Newton's constant in the Friedmann equations, ii) has zero press","authors_text":"Alexander Vikman, Leila Mirzagholi","cross_cats":["astro-ph.CO","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-12-22T20:29:17Z","title":"Imperfect Dark Matter"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1412.7136","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:e58084f3f6f9111f186ff90e64c39f24012a6b6d81e7cbf0ad2a2d312c5b6d4e","target":"record","created_at":"2026-05-18T01:42:47Z","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":"1ab90eb92207314ce7b1e88c2747367222048b5c106580a8571f2a3a5b137f5b","cross_cats_sorted":["astro-ph.CO","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2014-12-22T20:29:17Z","title_canon_sha256":"c52908a98f803007b349cd6e6815f2e95cb5f93bedeb8e24822fe44b92e2fe29"},"schema_version":"1.0","source":{"id":"1412.7136","kind":"arxiv","version":2}},"canonical_sha256":"2da6f077482c1405a40948b950943a08915dc502116b7e31a7436c8adf51fb4f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2da6f077482c1405a40948b950943a08915dc502116b7e31a7436c8adf51fb4f","first_computed_at":"2026-05-18T01:42:47.864272Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:42:47.864272Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"AARrUyoknpyJsG/iDTpICpTb//zRpZzlG38MMGYunsp7af6SbQEGa/LfqeKYrstvvRx8oijmRzeALJ1Q2hD2Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:42:47.864829Z","signed_message":"canonical_sha256_bytes"},"source_id":"1412.7136","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e58084f3f6f9111f186ff90e64c39f24012a6b6d81e7cbf0ad2a2d312c5b6d4e","sha256:4429326aa5f0ba21607522b0d0341d62275d66b61fdcd06944f5c5609d13b6de"],"state_sha256":"3df46e58f3b7d0aecccb1950885ff2285c2eac2cf8fea3c50beeb2f26a11afcb"}
