The state is characterized by the exponential decay of singlet-singlet correlations, whereas dimer-dimer correlations decay with a power law in the corresponding Quantum Dimer model. This observation leads to a novel mechanism for thermal Order by Disorder whereby thermal decoherence suppresses destructive quantum interference between different contributions to the correlations in the ground state and results in a qualitatively different, quasi-long-range ordered mixed state.","authors_text":"Giorgi Gogaberishvili, Kirill Shtengel, Nika Kurdadze","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2026-07-17T10:22:29Z","title":"Thermal Order by Disorder in Resonating-Valence Bond States on the Checkerboard Lattice"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.15813","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":"sha256:83bc153f83e1aa19fb78f6122e588a156dab45ac6fd5a8a689cf6d931164366c","target":"record","created_at":"2026-07-20T01:19:11Z","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":"0307d19cd37c6f96a1d2beed3137b1b1253e9616da9383134ea6c2e3cb024b01","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.str-el","submitted_at":"2026-07-17T10:22:29Z","title_canon_sha256":"68dd6b081959757e78e7545f2684eb27a3d7aac3f5e72c9daa6d28307800ced3"},"schema_version":"1.0","source":{"id":"2607.15813","kind":"arxiv","version":1}},"canonical_sha256":"a44fb910c17977ed276c1ece2bf941fb38035e15faa0f0d7062710c78fa1bd52","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a44fb910c17977ed276c1ece2bf941fb38035e15faa0f0d7062710c78fa1bd52","first_computed_at":"2026-07-20T01:19:11.721283Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-20T01:19:11.721283Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eSdTJxpWRCKCiqZr642Jqbt8BVIL4VzLtsM+q4nzMLE8QcMaNlEgrkjSEIBzDD8TUomPIMQUX8TK2saeynHIAQ==","signature_status":"signed_v1","signed_at":"2026-07-20T01:19:11.722209Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.15813","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:83bc153f83e1aa19fb78f6122e588a156dab45ac6fd5a8a689cf6d931164366c","sha256:dee1ea1e5ca3c19a83f90ebba16b48824ce1c3a914ab76fcb6fe2224889bb259"],"state_sha256":"c9e2f9a031c4c5f20add3f92d222173f069374fbae6b955b46f9ea7c71330b81"}
