چکیده انگلیسی
Superconducting proximity effect in normal metal (N)/triplet p-wave superconductor (P) junctions is studied on the basis of the quasiclassical Green's function theory. We assume the attractive interelectron potentials which can induce subdominant s-wave pair potentials in the N side, where spatial dependencies of the pair potentials are determined self-consistently. In the case of an N/px-wave junction, a zero-energy peak (ZEP) in tunneling spectra emerges due to the spin-commutated proximity effect through Andreev reflection in low barrier. Moreover, by varying the transparency of the junction, we obtain the broad line shaped tunneling spectra with the sharp ZEP similar to actual experiment of Ru/Sr2RuO4. In high barrier, our obtained results are consistent with previous works in isolated p-wave superconductors.
