In this work, we address this issue by conducting Monte Carlo simulations not only for $\\mathcal{N}=(2,2)$ but also for $\\mathcal{N}=(8,8)$ SYM in two dimensions for the U(N) theories with N=2, using the new ideas derived from topological twisting followed by geometric discretization. Our results from simulations provide the evidence that these theories do {\\it not} suffer from a sign problem as the co","authors_text":"Anosh Joseph, Dhagash Mehta, Richard Galvez, Simon Catterall","cross_cats":["hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2012-01-09T21:15:46Z","title":"Investigating the sign problem for two-dimensional $\\mathcal{N}=(2,2)$ and $\\mathcal{N}=(8,8)$ lattice super Yang--Mills theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1201.1924","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:c0ae1a27df969c5f89b60845b825493216f43fdb7b00cbe095610e018070b262","target":"record","created_at":"2026-05-18T04:04:54Z","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":"4d2053a29345e2fb9da485968f56f2941d9fdda7d26bf0706994caab8cd49071","cross_cats_sorted":["hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2012-01-09T21:15:46Z","title_canon_sha256":"9c2f0a4e74e67106cf73c691acf7a8d65810633326e1011906047cdea8bb42bf"},"schema_version":"1.0","source":{"id":"1201.1924","kind":"arxiv","version":1}},"canonical_sha256":"bfec52e59d2822d15ab9bf525bbd8eb6ab525e5a5e5da0243f6a6342da2d7026","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bfec52e59d2822d15ab9bf525bbd8eb6ab525e5a5e5da0243f6a6342da2d7026","first_computed_at":"2026-05-18T04:04:54.407108Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:04:54.407108Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"4hGlwEebZh2eNJpH2/MLA+At+OIFTUMoA/KVnwt1K9fZrzOhOCTxg9Hx/kdjSZ231ZeEJeWWwa7Ju6Ri2u2QAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:04:54.407704Z","signed_message":"canonical_sha256_bytes"},"source_id":"1201.1924","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c0ae1a27df969c5f89b60845b825493216f43fdb7b00cbe095610e018070b262","sha256:4fc68860af82d0a9b3b003541fed7b4c722749706ca09c27187132ea452dca02"],"state_sha256":"7d7267ae277cccd3dbcdf9551c1e45695b723fd62030d0e4d2b63257d1e87dcf"}
