| Abstract: | We discuss the Josephson current between two noncentrosymmetric superconductors. The coexistence of superconducting order parameters between the spin-singlet ΔS and the helical p-wave spin-triplet ΔT enriches a variety of low-temperature behavior of the Josephson current depending on their relative amplitudes. We will show that characteristic behaviors of the Josephson current for ΔS > ΔT are clearly different from those for ΔS < ΔT. The topologically protected zero-energysurface bound states are responsible for the clear difference. We conclude that the Josephson current reflects well the character of the topological surface states and the pairing symmetry of noncentrosymmetric superconductors. |
