We find that the effect is amplified by a factor $(E_F/\\Delta)$, with $E_F$ the Fermi energy and $\\Delta$ the gap. Interestingly, the GH effect appears only as a time delay $\\delta t$ without any lateral shift, and the corresponding delay length is about $(E_F/\\Delta)\\lambda_F$, with $\\lambda_F$ the Fermi wavelength. This makes the NS interface \"sticky\" when $\\Delta \\ll E_F$, since typically GH effects are of wavelength order. This \"sticky\" behavior can be further enhanced by a "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.6188","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"}
