- 論文の詳細を見る
Josephson effect between two Sr_2RuO_4 (SRO) is theoretically studied based on a new formula of Josephson current. We analytically calculate the Josephson current in clean SRO/insulator/SRO junctions and SRO/dirty normal metal/SRO junctions. In SRO, we assume a spin-triplet p wave superconductivity which breaks the chiral symmetry. When the current flows in a direction perpendicular to the c axis of SRO, the zero-energy states formed at the junction interfaces enhance the Josephson current in low temperature regime. We also report the Josephson current parallel to the c axis.
