摘要：

We discuss the Josephson effect in a spin-singlet superconductor/spin-triplet superconductor junction fabricated on a substrate. Due to inversion symmetry breaking on top of the substrate, Rashba spin-orbit interaction works on electrons in the superconductors. As a result, spin-triplet (spin-singlet) Cooper pairs are induced in a spin-singlet (spin-triplet) superconductor. The presence of such induced Cooper pairs enables the lowest-order Josephson coupling between the two superconductors. Based on the theoretical results and recent experimental findings [X. Xu et al., Phys. Rev. Lett. 132, 056001 (2024)], we analyze the pair potential of 3-Bi2Pd.
