抜粋

The Josephson current-phase relations in d-wave/d-wave superconductor junctions in the tunnel limit are studied using the two-dimensional t-J model. The order parameters are determined in a self-consistent way within the Gutzwiller approximation and the Bogoliubov-de Gennes theory. We find that the anomalous current-phase relation in (110) junctions obtained within a quasiclassical theory is qualitatively reproduced with microscopic model calculations. Our method can be applied to grain boundary junctions in which the atomic scale roughness should be taken into account.
