我们计算了倾斜晶界附近的s波和d波超导体序参量。我们这样做的Bogoliubov德Gennes方程内自洽，使用一个现实的微观模型的晶界。我们提出了第一个自洽计算的超导电流在这样的边界，获得的电流相位特性的晶界在s波和d波超导体。
We calculate the s- and d-wave superconductor order parameter in the vicinity of a tilt grain boundary. We do this self-consistently within the Bogoliubov de Gennes equations, using a realistic microscopic model of the grain boundary. We present the first self-consistent calculations of supercurrent flows in such boundaries, obtaining the current-phase characteristics of grain boundaries in both s-wave and d-wave superconductors.
