Figure 2
Andreev bound states and their energy dispersion.
(a) Quasiclassical trajectories of the Andreev bound states in the radially step-like order parameter. The bound states are depicted as electrons (solid arrow) being Andreev reflected as a hole (dashed arrow). Here b denotes the distance of the linear reflection path from the center of the 2D potential. (b) Example of a line profile of the order parameter corresponding to panel (a). Panel (c) shows the quasiparticle dispersion of lowest energy states for the step-like potential featured in panel (b).
