Abstract
We study the anomalous Josephson current appearing at zero phase difference in triplet superconductor–ferromagnet–triplet superconductor (TFT) junctions. The anomalous Josephson current appears when the magnetization orientation of the ferromagnet layer and two d vectors of triplet superconductors are noncoplanar. The Josephson junction involving two triplet superconductors with noncolinear d vectors exhibits two spin-split Andreev bound states which have opposite phase shifts compared with the conventional current-phase relation. The ferromagnet layer can transmit one of the Andreev bound states while block the other completely. The survived Andreev bound state gives rise to the anomalous Josephson current and have arbitrary equilibrium phase difference. The equilibrium phase difference of the supercurrent can be tuned continuously by the junction parameters.
