This model describes the $s={1 \\over 2}$ Heisenberg spin model with the anisotropic exchange coupling $J_{\\bot}=-\\alpha J_z$ and doped {\\it bosonic} holes, which is an effective system of the Bose-Hubbard model with strong repulsions. The bosonic \"electron\" operator $B_{r\\sigma}$ at the site $r$ with a two-component (pseudo-)spin $\\sigma (=1,2)$ is treated as a hard-core boson operator, and represented by a composite of two slave particles; a \"spinon\" described by a Schwinger b"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1111.1537","kind":"arxiv","version":2},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
