In particular we prove that a Planck-scale induced deformation of the Minkowski energy-momentum dispersion relation $\\delta E \\simeq \\xi_1 mcp/2M_p$ produces a shift in the condensation temperature $T_c$ of about $\\Delta T_{c}/T_{c}^{0} \\simeq 10^{-6} \\xi_1 $ for typical laboratory conditions. Such a shift allows to bound the deformation parameter up to $|\\xi_1| \\lesssim 10^4$. Moreover we show that it is possible to enlarge $\\Delta T_{c}/T_{c}^{0}$ and improve the bound on $\\xi_1$ loweri"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1206.1236","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"}
