Machine-learned coarse-graining (MLCG) has recently emerged as a promising approach to construct highly accurate force fields for CG molecular dynamics. However, the calibration of MLCG force fields typically hinges on force matching, which demands extensive reference atomistic trajectories with corresponding force labels. In practice, atomistic forces are often not recorded, making traditional force matching infeasible on pre-exist","authors_text":"Aleksander Durumeric, Atharva Kelkar, Frank No\\'e, Leon Klein, Yaoyi Chen","cross_cats":["cs.LG","physics.comp-ph","stat.ML"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2025-06-24T13:51:20Z","title":"Operator Forces For Coarse-Grained Molecular Dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.19628","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:e9df713b40877a64a1c19da4ba6843430c6e766d6c35f6f0dbd5a29065ea97df","target":"record","created_at":"2026-07-05T11:26:35Z","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":"357dc058bc5051967ebdc03a152d952a08944fc27c1678ca65b577dd7f3d9236","cross_cats_sorted":["cs.LG","physics.comp-ph","stat.ML"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2025-06-24T13:51:20Z","title_canon_sha256":"79abcb5b66a750e682a5882b861110e8f66e6878bd1c725a04355519c27e5ef1"},"schema_version":"1.0","source":{"id":"2506.19628","kind":"arxiv","version":1}},"canonical_sha256":"acd2271038e27ae8c855e76bce93f8d46f2675effc990ab7aa1ddf1c479ff832","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"acd2271038e27ae8c855e76bce93f8d46f2675effc990ab7aa1ddf1c479ff832","first_computed_at":"2026-07-05T11:26:35.824978Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:26:35.824978Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iTQcEInqWgJ6ngZMn199ZeaI7HJEeDmOd7sJIOqqPtH30OLGZ8Q4xyvfzoudkODW7KIb3DTLgzyxC+NhI+01Dw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:26:35.825466Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.19628","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e9df713b40877a64a1c19da4ba6843430c6e766d6c35f6f0dbd5a29065ea97df","sha256:21d4227adb8db261360675fba093a7d785db625d3061d185a1b54e1559de3018"],"state_sha256":"764ccf26c884a3ca56d1ac1a5f6295daf242a9488294de1d91a1d8699f591712"}
