The AC conductivity of samples with hole densities from $3.9 \\times 10^{11}$~to $6.2 \\times 10^{11}~\\text{cm}^{-2}$ was measured in perpendicular magnetic fields up to $8~\\text{T}$ using a contactless acoustic method. From the analysis of the temperature dependence of conductivity oscillations, the $\\mathrm{g}_{\\perp}$-factor of each sample was determined. The $\\mathrm{g}_{\\perp}$-factor was found to be decreasing approximately linearly with hole density. This effect is attributed to non-parabo"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.03876","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"}
