By solving the self-consistently coupled equations of dynamical fermion gap $m$ and disorder scattering rate $\\Gamma$, we found a critical line on the plane of interaction strength $\\lambda$ and disorder strength $g$. The phase diagram is divided into two regions: in the region with large $\\lambda$ and small $g$, $m \\neq 0$ and $\\Gamma = 0$; in the other region, $m = 0$ and $\\Gamma \\neq 0$ for nonzero $g$. In particular, there is no coexistence of finite fermion gap and finite scatter"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.4538","kind":"arxiv","version":4},"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"}
