This can lead to simulation runs that are effectively stuck in one topological sector, a problem known as topological freezing. Here, we demonstrate that for a relevant set of parameters, Metadynamics can be used to unfreeze 4-dimensional SU(3) gauge theory. However, compared to local update algorithms and the Hybrid Monte Carlo algorithm, the computational overhead is significant in pure gauge theory, a","authors_text":"Christian Hoelbling, Gianluca Fuwa, Lukas Varnhorst, Timo Eichhorn","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-lat","submitted_at":"2023-07-10T17:53:09Z","title":"Parallel Tempered Metadynamics: Overcoming potential barriers without surfing or tunneling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2307.04742","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":"sha256:049d43dfb0e0ceb10a7658e629946e087d74bfcf6ed97c7d75bab2a4cedd71d1","target":"record","created_at":"2026-07-05T08:29:44Z","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":"141422770c84ab1b095aff1ab8a84225e5fa5b6758a0e10647e91a038e51447f","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-lat","submitted_at":"2023-07-10T17:53:09Z","title_canon_sha256":"50709e844fcb9c0836bdb69cf75397b6404e3bf747843275b25bd0ea2c4bd7b8"},"schema_version":"1.0","source":{"id":"2307.04742","kind":"arxiv","version":2}},"canonical_sha256":"b35ca91d7a5a8bcdaa3a3569ddf0e05da21cb4bb1c35be1c22b1f29ebba73364","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b35ca91d7a5a8bcdaa3a3569ddf0e05da21cb4bb1c35be1c22b1f29ebba73364","first_computed_at":"2026-07-05T08:29:44.289474Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:29:44.289474Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BAJNaTasOffgbU01tffj3ncVtZWvuJbHJPw2uPR6GhkSJUmi+rSSgImSvdNcqSRYAAyfjpmjoAzy9E9XRqa1Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:29:44.289941Z","signed_message":"canonical_sha256_bytes"},"source_id":"2307.04742","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:049d43dfb0e0ceb10a7658e629946e087d74bfcf6ed97c7d75bab2a4cedd71d1","sha256:4c2ccc7a6b987dbb35a240a48141270bc3a8c876103b48b72128b9d8104c055a"],"state_sha256":"c0932ad8513c214dfb073c5a3f8c06a41623d8db20e9540992ee081aa9ae7d59"}
