Spin-polarized Andreev bound states in a superconductor contacted with two ferromagnetic point contacts. The reflection amplitudes in both contacts have equal magnitude. The spin-mixing angles are θL,R . Shown is the spin-resolved density-of-states for quasiparticles traveling between the contacts, as a function of ε and θR in the superconductor, in the midpoint between the two contacts, for fixed θL. The distance between the contacts is two superconducting coherence lengths. Left for spin-up, right for spin-down.
