Abstract
We study the physical properties of an -wave–normal-metal–-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 time-reversal symmetry for generic orientations of the -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.
