Working in the coincident gauge, we incorporate the holographic principle into non-metric gravity with non-minimal matter coupling. To address the dynamical complexity, we adopt a reconstruction approach, deriving the matter density evolution from the modified field equations rather than imposing a conserved fluid a priori. We perform parameter estimation using the latest observational data, including Type Ia supernovae, BAO, and direct Hubble para","authors_text":"Cheng cheng, Shuangnan Chen, Xiaofeng Yang, Xiaolong He, Xuwei Zhang, Yangjun Shi, Yunliang Ren","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-06-22T08:03:36Z","title":"Reconstructing Barrow Holographic Dark Energy in $f(Q,T)$ Gravity and Cosmic Constraint"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.17933","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:d590b52e074b7fcbc97687c940033dc157630d3c4f4f385ea7f54cf5b47236e4","target":"record","created_at":"2026-06-02T01:03:32Z","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":"6efcb8e3cc0afd8e04c193e6bc2948931162580cd8fb465acef75353ee7c8f2c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-06-22T08:03:36Z","title_canon_sha256":"5424fd49e21f900b3d7e3cf7df392f2023e01c1eec7ebd289a9fa7787eb607d0"},"schema_version":"1.0","source":{"id":"2506.17933","kind":"arxiv","version":3}},"canonical_sha256":"b2ba13ee725d7988d284f47c50d4d056083f1232138eb87efbba7f1da09e26af","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b2ba13ee725d7988d284f47c50d4d056083f1232138eb87efbba7f1da09e26af","first_computed_at":"2026-06-02T01:03:32.350715Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-02T01:03:32.350715Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jrkj51x7WjtBoeGZmSZSCEaC0iPMzTktCmE73CdmCJsXgLDlvAoz7vXXbx3sTCexNIyCd4/thNke/nYzJJF/Cw==","signature_status":"signed_v1","signed_at":"2026-06-02T01:03:32.351519Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.17933","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d590b52e074b7fcbc97687c940033dc157630d3c4f4f385ea7f54cf5b47236e4","sha256:bfd5c274d21d7bd1e5c5b57b1f5a03598fc4b753e3d0bd1f3f675e2c11c778db"],"state_sha256":"b708ff9aacb5503d4cbb75d2887b829eea3bea7d5c2f72c6581ec78b8cd58076"}
