We assume that the pairing interaction is manifested between electrons of single-particle energies in an interval $[\\mu - \\hbar\\omega_c, \\mu + \\hbar\\omega_c]$, where $\\mu$ and $\\omega_c$ are parameters of the model--$\\mu$ needs not be equal to the chemical potential of the system, denoted here by $\\mu_R$. The BCS results are recovered if $\\mu = \\mu_R$. If $\\mu \\ne \\mu_R$ the physical properties change significantly: the energy gap $\\Delta$ is smaller than the BCS gap, a population imbalance app"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1604.07812","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"}
