论文摘要
从理论上讲，我们研究了$ d+ip $ - 波超导体的隧道电导率，该导电机最近被提议在高$ t_c $ cuprate超导体的（110）表面上实现。利用准经典艾伦伯格理论，我们获得了自洽的对电位和正常金属/$ d+ip $ - 波超导体连接的差分电导。我们证明，$ d $ - 波超导体的零偏置峰与旋转三个$ p $ p $ p $ p $ p $ p $ p $ p $ p $ p $ pub-wave Surface subdinant订单的零偏置峰值，即使它在旋转singlet $ s $ - $ - $ - 波较大的方面也很脆弱。比较我们的数值结果和实验结果，我们得出结论旋转三个$ p $ - 波级尺寸的顺序是可行的。
We theoretically investigate the tunneling conductance of the $d+ip$-wave superconductor which is recently proposed to be realised at the (110) surface of a high-$T_c$ cuprate superconductor. Utilizing the quasiclassical Eilenberger theory, we obtain the self-consistent pair potentials and the differential conductance of the normal-metal/$d+ip$-wave superconductor junction. We demonstrate that the zero-bias peak of a $d$-wave superconductor is robust against the spin-triplet $p$-wave surface subdominant order even though it is fragile against the spin-singlet $s$-wave one. Comparing our numerical results and the experimental results, we conclude the spin-triplet $p$-wave surface subdominant order is feasible.
