We construct the free energy landscape for this system, both in the continuum approximation using surfaces tensions and the flat-interface approximation and atomistically using MD and thermodynamic integration. The results of the two methods differ in detail due to interfacial distortion and finite width, as well as thermal fluctuations, and only the MD landscape is consistent with simulations of a nanosphere approaching ","authors_text":"Charles Maldarelli, Joel Koplik","cross_cats":["physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2018-08-24T21:36:10Z","title":"A Molecular Dynamics Study of The Translation and Rotation of Amphiphilic Janus Nanoparticles at a Vapor-Liquid Surface"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.08318","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":"sha256:26a04b3793cb793e7afcd2586fb98216856c0fdf724cbfb196d6a1196e5aa338","target":"record","created_at":"2026-05-17T23:48:23Z","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":"931f94a23fd4d3c2fc2e4d83af6441d4b86e3d8412af76a055ff7b2c715ec662","cross_cats_sorted":["physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2018-08-24T21:36:10Z","title_canon_sha256":"f14f822010a335d3ce1d0b918046134d61527963aca13634bb4cd4383aee7508"},"schema_version":"1.0","source":{"id":"1808.08318","kind":"arxiv","version":1}},"canonical_sha256":"240d9c1895fc06b382542a6ad0b941ec9e9ea5700908cee9da1d2fdf834c37e1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"240d9c1895fc06b382542a6ad0b941ec9e9ea5700908cee9da1d2fdf834c37e1","first_computed_at":"2026-05-17T23:48:23.779782Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:48:23.779782Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Id/NPvPcEOuj/2gjegwI0RYKgwccsgx/wsUU8sSRVZ9oLqgc9x96vE8aGR9RmZeQKp/98043qR+lM5Wqag9/Aw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:48:23.780357Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.08318","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:26a04b3793cb793e7afcd2586fb98216856c0fdf724cbfb196d6a1196e5aa338","sha256:00c6465e24902014035c1e25b00484d8a4b6659186c89e1e0e731875be473aae"],"state_sha256":"03e3b1edd773197309ea4755fa35a476535241aaac0b3d06f9ae96e799c00201"}
