Relying on the rich quantum-simulation toolbox available in state-of-the-art trapped-ion experiments, we show how one can engineer an effectively gauge-invariant dynamics by imposing energetic constraints, provided by strong Ising-like interactions. Applying exact diagonalization to ground-state and time-dependent properties, we study the underlying microscopic model, and discuss undesired i","authors_text":"David Marcos, Marcello Dalmonte, Peter Zoller, Philipp Hauke","cross_cats":["cond-mat.str-el","hep-lat","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2013-06-10T10:44:29Z","title":"Quantum simulation of a lattice Schwinger model in a chain of trapped ions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1306.2162","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:bacaa173977e090805a5f033830ada84f81459c62e55cf781eabdd71e9994a24","target":"record","created_at":"2026-05-18T03:05:28Z","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":"8631e5cfbba1d1ebdc07b8be0d70f5a23ca2971d677d7116464ba51d61df98d7","cross_cats_sorted":["cond-mat.str-el","hep-lat","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2013-06-10T10:44:29Z","title_canon_sha256":"114f3b41e9a013507b6b2124b801d34bc5808126ccf6549a2e08c97813a2542b"},"schema_version":"1.0","source":{"id":"1306.2162","kind":"arxiv","version":3}},"canonical_sha256":"8307f81eaf2939314e0e4ff939adf37cdb94dddc5b8b09a5355853f88957c9c3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8307f81eaf2939314e0e4ff939adf37cdb94dddc5b8b09a5355853f88957c9c3","first_computed_at":"2026-05-18T03:05:28.087599Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:05:28.087599Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IJN5W1aZhh9becK0B4bmE3xlHYL1KKnVyUcZ+rIv9j2BgZvTsE3yQPx21k7VPCaz/huqZ01rixj/N2DouVg5Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:05:28.088161Z","signed_message":"canonical_sha256_bytes"},"source_id":"1306.2162","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bacaa173977e090805a5f033830ada84f81459c62e55cf781eabdd71e9994a24","sha256:ccac8eee97b44e0ce14c579745664d91fe07cb8366210af4733a308df0fe87ea"],"state_sha256":"8922de9037f31e505fb6c34da1312554b87be25c94b802012bbe8fce729f75be"}
