Anomalous shift in Andreev reflection from side incidence
Anomalous shift in Andreev reflection from side incidence
Andreev reflection at a normal-superconductor interface may be accompanied with an anomalous spatial shift. The studies so far are limited to the top incidence configuration. Here, we investigate this effect in the side incidence configuration, with the interface parallel to the principal axis of superconductor. We find that the shift …
