By performing a detailed Poisson-Schr\\\"odinger self-consistent calculation, we determine all the intra- and inter-subband Rashba ($\\alpha_1$, $\\alpha_2$, $\\eta$) and Dresselhaus ($\\beta_1$, $\\beta_2$, $\\Gamma$) coupling strengths. For relatively narrow wells with only one subband occupied, our results are consistent with the data of Koralek \\emph{et al.} [Nature \\bfs{48}, 610 (2009)], i.e., the Ra"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.7358","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"}
