Here, using quantum molecular dynamics simulations of nanoscale gold patches suspended in graphene pores, we predict the existence of an atomically thin, free-standing 2D liquid phase. The liquid phase, enabled by the exceptional planar stability of gold due to relativistic effects, demonstrates extreme fluxionality of metal nanostructures and opens possibilities for a variety of nanoscale phenomena.","authors_text":"Pekka Koskinen, Topi Korhonen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-05-20T13:58:45Z","title":"Plenty of motion at the bottom: Atomically thin liquid gold membrane"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1505.05387","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:eb06f83d743bc4de9e03438f1a061b346f26938cab3ceb16ef5ccfa3441c1a54","target":"record","created_at":"2026-05-18T01:34:49Z","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":"2dc5f342d9728439cb0d2589a0b8b137d9897c3f0bbf08778d60f4557eca54cf","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.mes-hall","submitted_at":"2015-05-20T13:58:45Z","title_canon_sha256":"fe4c2b7b8798736baa0724cdc3ed398cebc95195577e35abfc6057f0ed9869e4"},"schema_version":"1.0","source":{"id":"1505.05387","kind":"arxiv","version":2}},"canonical_sha256":"6d38b09cc0833973d345422616a60162e37eaf5870942ab647d1c79163fb8722","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6d38b09cc0833973d345422616a60162e37eaf5870942ab647d1c79163fb8722","first_computed_at":"2026-05-18T01:34:49.697927Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:34:49.697927Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WjSCko4d3jpO8LM5rqS/XVPA3KVcaBrYFysFQrGVSkqz8sf9Tbz9ll2TISu//3pKVLbGcgsn+3CRzvt3OzvLCw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:34:49.698463Z","signed_message":"canonical_sha256_bytes"},"source_id":"1505.05387","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eb06f83d743bc4de9e03438f1a061b346f26938cab3ceb16ef5ccfa3441c1a54","sha256:21028242f6742c1b44ec2c3b4b15a179f514b99205e90a791d69a6546567f9e3"],"state_sha256":"3a272fefa173c9e6dab41066388b1a73ee5b779f1411fd551e7b1ebd94daf11a"}
