The matter and radiation perfect fluids are modeled using the Sorkin-Schutz formalism. We identify scaling regimes of the field during both the radiation and matter eras. Additionally, we discovered a field-dominated scaling attractor; however, it does not exhibit accelerated expansion, making it unsuitable for describing dark energy. Nevertheless, we find two attractor solutions that do exhibit acceler","authors_text":"Carlos Rodriguez-Benites, Giovanni Otalora, Manuel Alva-Morales, Manuel Gonzalez-Espinoza","cross_cats":["astro-ph.CO","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2024-08-26T20:21:00Z","title":"Cosmological Dynamics in Interacting Scalar-Torsion f(T,$\\phi$) Gravity: Investigating Energy and Momentum Couplings"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2408.14614","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":"sha256:7497111330174a06c2bf1609c24c73f37b067d1bdb49df52ad02476a252cf5d7","target":"record","created_at":"2026-07-05T10:09:07Z","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":"534ac883c23e132ae3b5e38efc1798a0662f8dea2fcec2cb64260361da018b15","cross_cats_sorted":["astro-ph.CO","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2024-08-26T20:21:00Z","title_canon_sha256":"fb6ae6304c46ce1ff4befe8dc69210e66e594a2d2b6044c38386db2ae3f631a3"},"schema_version":"1.0","source":{"id":"2408.14614","kind":"arxiv","version":2}},"canonical_sha256":"dc9e1c25d304ade4093534e109c139f4876553e2f3b3862f51504073703a92b6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dc9e1c25d304ade4093534e109c139f4876553e2f3b3862f51504073703a92b6","first_computed_at":"2026-07-05T10:09:07.981636Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:09:07.981636Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NBZGCfX65wHr4zygH30AddHxEDItjPNQ2p6ASVAYIFA6pn3CKfgcnTWOH+0Kot+0P1sa5thXI4dM8J77MeX1BQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:09:07.982048Z","signed_message":"canonical_sha256_bytes"},"source_id":"2408.14614","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7497111330174a06c2bf1609c24c73f37b067d1bdb49df52ad02476a252cf5d7","sha256:187b09ef66f1224792533748839ec938a8fb6f86f766a341c687632d04788522"],"state_sha256":"212d8af79724927c6affae3ad8d68132a4856b3a2df130d96b23667c06cf611b"}
