摘要
We derive a formula of the dc Josephson current between two superconductors with anisotropic pairing symmetry. One of the basic characters in the junctions of the anisotropic superconductors is the formation of the zero-energy bound states at the junction interfaces, which leads to the low-temperature anomaly of the Josephson current. The contribution of the zero-energy states to the Josephson current is taken into account in the present formalism.
