To define notions of reference frames and switching of reference frames on a tensor network, we will borrow ideas from the algebraic quantum field theory literature. With these definitions, we construct simple examples of Lorentzian tensor networks and solve the spectrum for a choice of ``inertial frame'' based on Gaussian models of fermions and integrable models. In particular, the tensor network can be viewed as a ","authors_text":"Arpan Bhattacharyya, Ling-Yan Hung, Long Cheng, Sirui Ning, Zhi Yang","cross_cats":["cond-mat.str-el","gr-qc","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-05-08T14:48:19Z","title":"Notes on the Causal Structure in a Tensor Network"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.03071","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":"sha256:8723a389868c5a2a51a2364eea56099a59a215ddeb339b1fb5cb9127c64d4196","target":"record","created_at":"2026-05-17T23:48:40Z","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":"735c668d7b60903f1d2ad9ed943d1975d4d94786546d1659ef0a1ffcb3f216fe","cross_cats_sorted":["cond-mat.str-el","gr-qc","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2018-05-08T14:48:19Z","title_canon_sha256":"1810ff7727dcc50a44ed9565c507625c80ea04f52b61adeb6a7f83a6afab9b8d"},"schema_version":"1.0","source":{"id":"1805.03071","kind":"arxiv","version":3}},"canonical_sha256":"ee5329cfb9b9eba05873e94575d993d44679c5b554e97e8329c49200f9476838","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ee5329cfb9b9eba05873e94575d993d44679c5b554e97e8329c49200f9476838","first_computed_at":"2026-05-17T23:48:40.517959Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:48:40.517959Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZMbmM5dLuJtCwbYCfPDujFt1XGQ8i9061Xi0t5PZkxXI6WP0j0u/IgVpafMMBT+hZ86HecK8jnLHQRJCmEDQCQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:48:40.518515Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.03071","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8723a389868c5a2a51a2364eea56099a59a215ddeb339b1fb5cb9127c64d4196","sha256:9a3dc5aaefb14cf7960e142a9394bb91265087414fc18a57fc788a179b0a36f1"],"state_sha256":"04b5024d801f305d71b42fadd896faa65cd3342d6c17342c875f642ad3b305d1"}
