Abstract:We study the Josephson effect in a clean noncentrosymmetric superconductor/half-metal/noncentrosymmetric superconductor junction, which is grown on the surface of a three-dimensional Topological Insulator (TI) in the ballistic limit. We find the signature of anomalous Andreev Bound States (ABS) and band splitting for a spinactive barrier whose barrier magnetic moment is misaligned with the bulk moment. The chiral Majorana mode and 4π periodic ABS are found to exist on the surface of TI for parallel orientation… Show more
