This technique is applied to the antiferromagnetic Ising model in an external magnetic field on the square lattice, which is simulated using the tomographic entropic sampling algorithm. We estimate the number of configurations, $\\Omega(E,m,L)$, and related microcanonical averages, for all allowed energies $E$ and magnetizations $m$ for $L = 10$ to 30, with $\\Delta L = 2$. With prior knowledge of the CCs, we can be sure that all allowed classes a","authors_text":"Bruno Jeferson Louren\\c{c}o, Ronald Dickman","cross_cats":["physics.comp-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2011-12-06T19:51:20Z","title":"Systematic enumeration of configuration classes for entropic sampling of Ising models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1112.1387","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":"sha256:484047a1195ca8583b860d0b5cfb4c45e30f68f93dcf6793a32709e4cf37cfbc","target":"record","created_at":"2026-05-18T04:06:55Z","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":"26105025de49ee975585bc7c816633dabc3f864bbeba9756f74c7868f594b12f","cross_cats_sorted":["physics.comp-ph"],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2011-12-06T19:51:20Z","title_canon_sha256":"2b9e1b6a4f6f2162155954a2519bab3a0b9caedcc43bd20ece4eba51ab605954"},"schema_version":"1.0","source":{"id":"1112.1387","kind":"arxiv","version":1}},"canonical_sha256":"9c879017d36fc6b2d9690587f690c56e8d53d3572265817ff252b345c0631d3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c879017d36fc6b2d9690587f690c56e8d53d3572265817ff252b345c0631d3c","first_computed_at":"2026-05-18T04:06:55.531638Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:06:55.531638Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PBpBYhSYrQCmVRSDIEWziMo/11yhO6h7QpMTEWzoEMI+vvpHVCpt0OTS6+7HA51MEpUHtzPz3wmBMSJqyDTmAw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:06:55.532244Z","signed_message":"canonical_sha256_bytes"},"source_id":"1112.1387","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:484047a1195ca8583b860d0b5cfb4c45e30f68f93dcf6793a32709e4cf37cfbc","sha256:f354ceca9652f14fc24071ce3762416368226781674e389e22e9dc566a9d737b"],"state_sha256":"170b13b2b53fdc1dd22f892426fc2b60062ba394d46448f9081d302ac9f7550a"}
