“…In ZS/N/ZS junctions, the spin degeneracy of the Andreev level is lifted and the magnitude of the spin splitting can be controlled by changing either the magnitude or relative direction of the Zeeman field in the superconducting leads [16][17][18][19]. ZS/N/ZS junctions with unconventional superconducting pairing such as por d-wave pairing, have also been studied and the tunability of the Andreev level by changing the relative direction of the Zeeman field and superconducting d-vector have been demonstrated [20][21][22][23].…”

We study Andreev reflection and Andreev levels ε in Zeeman-split superconductor/Rashba wire/Zeeman split superconductor junctions by solving the Bogoliubov-de Gennes equation. We theoretically demonstrate that the Andreev levels ε can be controlled by tuning either the strength of Rashba spin-orbit interaction or the relative direction of the Rashba spin-orbit interaction and the Zeeman field. In particular, it is found that the magnitude of the band splitting is tunable by the strength of the Rashba spin-orbit interaction and the length of the wire, which can be interpreted by a spin precession in the Rashba wire. We also find that if the Zeeman field in the superconductor has the component parallel to the direction of the junction, the ε-φ curve becomes asymmetric with respect to the superconducting phase difference φ. Whereas the Andreev reflection processes associated with each pseudospin band are sensitive to the relative orientation of the spin-orbit field and the exchange field, the total electric conductance interestingly remains invariant.
