Figure 2From: Tunable spin-dependent Andreev reflection in a four-terminal Aharonov-Bohm interferometer with coherent indirect coupling and Rashba spin-orbit interactionThe AR conductance versus Fermi energy for P and AP configurations. (a) α = 0, (b) α = 0. 5, and (c) α = 1. 0. Other parameters are ε1 = ε2 = 0, tc = 0. 5, ϕ = 0, and φR = Π/2.Back to article page
