Eto, M. Nazarov, Y.V. Faculty Applied Sciences Department QN/Quantum Nanoscience Date 2012-07-29 Abstract We theoretically study the current-phase relation in semiconductor nanowire Josephson junction in the presence of spin-orbit interaction. In the nanowire, the impurity scattering with strong SO interaction is taken into account using the random matrix theory. In the absence of magnetic field, the Josephson current I and phase difference ? between the superconductors satisfy the relation of I(?) = –I(–?). In the presence of magnetic field along the nanowire, the interplay between the SO interaction and Zeeman effect breaks the current-phase relation of I(?) = –I(–?). In this case, we show that the critical current depends on the current direction, which qualitatively agrees with recent experimental findings.
