However, conventional approaches such as Monte Carlo (MC) simulations in imaginary time are limited, as they do not allow real time evolution and suffer from a sign problem in many important cases. Using Gauged Gaussian fermionic projected entangled pair states (GGFPEPS) as a variational ground state ansatz offers an alternative for studying LGTs through a sign-problem-free variational MC. As this method is extended to larger and more complex systems, understanding its numerica","authors_text":"Ariel Kelman, Erez Zohar, Itay Gomelski, Jonathan Elyovich, Patrick Emonts","cross_cats":["cond-mat.str-el","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2025-12-15T19:01:02Z","title":"Algorithmic Aspects of Gauged Gaussian Fermionic PEPS: Gauge Fixing and Translation Invariance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2512.13812","kind":"arxiv","version":2},"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":"sha256:6b85b0e30c8bbcc76b8803ef35e1ffd8e6c59d45185b352f1eb676012ee64bf9","target":"record","created_at":"2026-07-01T01:17:12Z","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":"28781c55fda6f2409b986b9a56b2a1bfdef6280852a85bbbdc9194358aa5f4f9","cross_cats_sorted":["cond-mat.str-el","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2025-12-15T19:01:02Z","title_canon_sha256":"63ac156e4def3a90fd64488469ce41ad3d75aaa291b9158a3de652290eeff4be"},"schema_version":"1.0","source":{"id":"2512.13812","kind":"arxiv","version":2}},"canonical_sha256":"ef0a5d658aca6b5b5bedcdf5842a5ab424ca618e7326a5746920bd50490c53c4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ef0a5d658aca6b5b5bedcdf5842a5ab424ca618e7326a5746920bd50490c53c4","first_computed_at":"2026-07-01T01:17:12.273393Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-01T01:17:12.273393Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wtT3x0mbGsFeX7Zotd2GpQK+BdqHbMkPamYIMBD4MflTqLiNSUx2KFowqTnLFZuvlXKysEqEBdv9+goUKxCHAw==","signature_status":"signed_v1","signed_at":"2026-07-01T01:17:12.273935Z","signed_message":"canonical_sha256_bytes"},"source_id":"2512.13812","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6b85b0e30c8bbcc76b8803ef35e1ffd8e6c59d45185b352f1eb676012ee64bf9","sha256:00bea2e2a494568308a65b23c59f1718869d13abf80c4760d667d807d45c1397"],"state_sha256":"2ca5f8027f08fe825d0139868984afde03b1beeb868ce231f743d2f4c3919e4b"}
