The peculiar random-regular nature of the lattice is meant to account for the formation of a random 4-coordinated hydrogen-bond network. The model turns out to be consistent with most thermodynamic anomalies observed in liquid and supercooled-liquid water. Furthermore, the model exhibits two glassy phases with different densities, which can coexist at a first-order transition. The onset of a complex free-energy landscape, characterized by an exponentially large number of metastable minima, is pointed out by ","authors_text":"Andrea Pagnani, Marco Pretti","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2010-06-09T09:18:07Z","title":"A discrete model of water with two distinct glassy phases"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1006.1750","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":"sha256:47ced3b6886822df0920fcecd7851aed85e9cb27d4d261b15525b169ce0c55f3","target":"record","created_at":"2026-05-18T02:06:55Z","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":"55216dfcd1019010d6e416b81a64397776cb7cb9f1dd9a05eb882efaa606d04e","cross_cats_sorted":["cond-mat.stat-mech"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2010-06-09T09:18:07Z","title_canon_sha256":"7233e2dcb4d6b99c1246d4df100ac155ca18ba1a0ad7a76e7ed27dd1db500d68"},"schema_version":"1.0","source":{"id":"1006.1750","kind":"arxiv","version":2}},"canonical_sha256":"76a036232bf06734d0bd37a0272a28fac1c942d36b869f2102e0eb2c4791df54","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"76a036232bf06734d0bd37a0272a28fac1c942d36b869f2102e0eb2c4791df54","first_computed_at":"2026-05-18T02:06:55.682848Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:06:55.682848Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xeCsNSMO/wwSFs5JHLWPzrnhBnnDbMR61t3uKoXvR7bqi+hd+fvqFz9+FKIwPHtLgn7D4InvtZgz7Vs76b+hDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:06:55.683585Z","signed_message":"canonical_sha256_bytes"},"source_id":"1006.1750","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:47ced3b6886822df0920fcecd7851aed85e9cb27d4d261b15525b169ce0c55f3","sha256:c925c850b4cc733550a8db20283595b8b90fc7156749e1f6ff375e74680d5e34"],"state_sha256":"14986df7b38a36bba6891b5f1b6cb8b713bc8da78ddee3acf99f0e907392cfd6"}
