We find that above the critical temperature the frequency dependent flux noise $S_{\\Phi}(\\omega)\\sim \\vert 1+ {(\\omega/\\Omega)}^2\\vert^{-\\alpha (T)/2}$, with $0.85\\leq \\alpha (TDGL)(T)\\leq 0.95$ and $1.17 \\leq \\alpha (RSJ)(T) \\leq 1.27$, while the dynamic critical exponents $z(TDGL)\\sim 2.0$ and $z(RSJ)\\sim 0.9$. Contrary to expectation the TDGL results are in closer agreement with th"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"cond-mat/9611208","kind":"arxiv","version":1},"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"}
