摘要：

We study the physical properties of an s-wave-normal-metal-d-wave junction in terms of the Andreev bound-state solutions to the Bogoliubov-de Gennes equation in the normal-metal layer. The phase dependence of bound states with different orientations leads to superconducting states with broken rime-reversal symmetry for generic orientations of the d-wave superconductor crystal. The occurrence of such a state and the associated spontaneous supercurrent along the junction and magnetic field is analyzed also in the framework of Ginzburg-Landau theory.
