For certain orientations of Josephson junctions between two px-wave or two d-wave superconductors, the subgap Andreev bound states produce a 4π-periodic relation between the Josephson current I and the phase difference:φ I sin(φ/2). Consequently, the ac Josephson current has the fractional freque...
