However, by construction, in this formalism the Hilbert space of the gauge fields is truncated to a finite number of irreducible representations of the gauge group. We investigate quantitatively the influence of the truncation of the infinite number of representations in the Schwinger model, one-flavour QED$_2$, with a uniform electric background field. We compute the two-site reduced density matrix of ","authors_text":"Boye Buyens, Frank Verstraete, Jutho Haegeman, Karel Van Acoleyen, Simone Montangero","cross_cats":["cond-mat.str-el","hep-th","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2017-02-28T16:12:55Z","title":"Finite-representation approximation of lattice gauge theories at the continuum limit with tensor networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.08838","kind":"arxiv","version":1},"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:c05d6ffe2817fb6cd5ea957362340da0e9d993059be5d367d6ce3830a8881b4d","target":"record","created_at":"2026-05-18T00:43:39Z","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":"d83c80da4ecbec2a0a8bfb9d21602464abc9a407891e8de9617c65e84a7525fd","cross_cats_sorted":["cond-mat.str-el","hep-th","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2017-02-28T16:12:55Z","title_canon_sha256":"6202f4d604a0df069fa964cd78220341ec4ba7b39d6e10059500eaf055593b0a"},"schema_version":"1.0","source":{"id":"1702.08838","kind":"arxiv","version":1}},"canonical_sha256":"19c3bb1da5366eccde3c446a9141537daac1a6b86b1e5c55d8e2d9a60e7a7a0e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"19c3bb1da5366eccde3c446a9141537daac1a6b86b1e5c55d8e2d9a60e7a7a0e","first_computed_at":"2026-05-18T00:43:39.332413Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:43:39.332413Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HNOGfCz9FDtO4tU1aNjniwb0tSVUx87LAcfjD0/o9ljqGBolHMlawLT7wxgaiLpE6Gnb9B4+nm42zfKD+yTICw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:43:39.332978Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.08838","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c05d6ffe2817fb6cd5ea957362340da0e9d993059be5d367d6ce3830a8881b4d","sha256:d0f50c9731d78855133f9cfb06ca54a03dbd09947832e0e223dd15dc3efe446d"],"state_sha256":"4d2ec5d2c210fd17c8fba2b001fe2c480434a7fba3785a2cd795a09012c6c724"}
