Andreev bound state in a superconducting double barrier junction: The role of anisotropic dx2−y2-wave pairing potential

In this study, we have investigated the transport properties in the superconducting double barrier junction, considering unconventional anisotropic d-wave pairing potential. It is shown that the Andreev bound state and the spin conductance of such system exhibit essential different features, as compared to the results in the conventional isotropic s-wave superconducting double barrier junction.
