The general expression for the absorption coefficient ($\\Gamma$) under a non-quantizing electric field ($E$) with drift velocity ($V_D$)was obtained. At $T = 10K$ and scattering angle $\\theta > 0$, the dependence of $\\Gamma$ on acoustic wave number ($\\vec{q}$), frequency ($\\omega_q$), and $\\gamma = 1-\\frac{V_D}{V_s}$, ($V_s$ being the speed of sound) were analysed numerically at $n = 0, \\pm 1, \\pm 2$ (where $n$ represent th"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1502.07636","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"}
