We present a new classical non-polarizable force field for this molten salt mixture, optimized using experimental and first principles molecular dynamics simulations as reference data. This simple force field allows efficient molecular simulations of phenomena at long timescales. We use this optimized force field to describe the behavior of the eutectic mixture in the 900-1100 K temperature range, at pressures between 0 and 5 GPa","authors_text":"Dario Corradini, Fran\\c{c}ois-Xavier Coudert, Rodolphe Vuilleumier","cross_cats":["cond-mat.mtrl-sci","physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2015-12-28T10:50:51Z","title":"Insight into the Li$_2$CO$_3$-K$_2$CO$_3$ eutectic mixture from classical molecular dynamics: thermodynamics, structure and dynamics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1512.08369","kind":"arxiv","version":3},"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:bbcc24cdeba41c2a24c732682e4ad943fc7dfd949e1fdde867f6350acd982ae6","target":"record","created_at":"2026-05-18T01:18:59Z","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":"f60b13b9cc67a501a5a303f7515708bd9cf3152d6555179f799472da413c8066","cross_cats_sorted":["cond-mat.mtrl-sci","physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2015-12-28T10:50:51Z","title_canon_sha256":"3457bb2477418777df0f37a912036e387fc2c73001c2e056ddafd43a49bbe919"},"schema_version":"1.0","source":{"id":"1512.08369","kind":"arxiv","version":3}},"canonical_sha256":"2fb24fabf87ad55f0642615621cd1023d800ed6a5840d10300c2a9bdd19e4c5a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2fb24fabf87ad55f0642615621cd1023d800ed6a5840d10300c2a9bdd19e4c5a","first_computed_at":"2026-05-18T01:18:59.996924Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:18:59.996924Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IXZPwh8R9HFPZAqNG1zF/qh8ThQRJvTd9w6R2iEghz09b9pxtxQHBHwd0s+SZew2yYkv2+E3VZd3m/3Gj30gDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:18:59.997392Z","signed_message":"canonical_sha256_bytes"},"source_id":"1512.08369","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bbcc24cdeba41c2a24c732682e4ad943fc7dfd949e1fdde867f6350acd982ae6","sha256:6505fd8bb3f6f236e76dcad060f3bd03770207a3ccb21052a9ff754677a28b8a"],"state_sha256":"9bd5bec9129d5c45d8cc36552a1b281937bb7bce1392284653738a48c13fd21f"}
