The coupling of spin $\\boldsymbol{\\sigma}$ with momenta $\\boldsymbol{p}$ is configured by a material dependent $3\\times 3$ matrix $\\boldsymbol{\\Lambda}$ as ${\\sigma}^\\mu {\\Lambda}_\\mu^\\nu p_\\nu$. We show that the spectra of the interface suggap states depend strongly on the relative choices of $\\boldsymbol{\\Lambda}$ in the two topological insulators. In particular, we focus on properties of gaple"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.4834","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"}
