In the dual representation the complex action problem at non-zero $\\theta$ is absent, which is an obstacle for Monte Carlo simulations in the conventional form of the model. We discuss the technical aspects of the dual representation and show that a dual Monte Carlo simulation can be implemented. As a first application we demonstrate how the $2\\pi$-periodicity of physical observables is recovered in a suitable continuum limit.","authors_text":"Christof Gattringer, Thomas Kloiber","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2014-10-13T08:27:51Z","title":"Scalar QED$_2$ with a topological term - a lattice study in a dual representation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.3216","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":"sha256:018340f5ad0ef520bc91adf39ee676b72361ad14b13e4e73322e93a52d4c701c","target":"record","created_at":"2026-05-18T02:40:11Z","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":"1421dcbf88e02492ebda498d1ed417d12270d689d228a23a4e32d91e3ee2be94","cross_cats_sorted":["cond-mat.stat-mech"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2014-10-13T08:27:51Z","title_canon_sha256":"fb19de97104d2d946c87fd3259b1e7aec2e4679c9833cc96e088a058a208cef1"},"schema_version":"1.0","source":{"id":"1410.3216","kind":"arxiv","version":1}},"canonical_sha256":"ea9df91689b7c7f09934c24897c4f4443d7b6f6a1951957b80dbef5657581c2a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ea9df91689b7c7f09934c24897c4f4443d7b6f6a1951957b80dbef5657581c2a","first_computed_at":"2026-05-18T02:40:11.820524Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:40:11.820524Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BvyRn+0EGws9VuwbXOVsswGrmwFGdqXy0IblImjFMVLTcR2yGhrhNzcGpsr2hUTXuc4JNsb3SNNlnaOIx2FmDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:40:11.821137Z","signed_message":"canonical_sha256_bytes"},"source_id":"1410.3216","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:018340f5ad0ef520bc91adf39ee676b72361ad14b13e4e73322e93a52d4c701c","sha256:08604b63491e70d9e8b965169e7e3ffd0bfe3b4070721fc4c761e5f03b3f4ef6"],"state_sha256":"35e5063253b377edbe6c3473e5f276b94dc449c2c1828e61ca2592efa3940d89"}
