Figure 5From: Tunable spin-dependent Andreev reflection in a four-terminal Aharonov-Bohm interferometer with coherent indirect coupling and Rashba spin-orbit interactionImages of spin-polarized AR current current as a function of QD levels ε 1 and ε 2 (Color on line). (a) α = −0.5 and (b) α = 0.5. Other parameters are ϕ=0, φ R = 0, tc = 0.5, and P L = P R = 0.4.Back to article page
