论文摘要
当通过自旋活性界面耦合到传统的$ s $ s $ s $ s $ s-wave旋转式超导体超导体时，我们探讨了接近诱导的奇数配对在铁磁体的热电上的作用。通过改变铁磁铁中的极化及其方向以及界面自旋轨道相互作用强度，我们分析了铁磁铁中所有接近诱导的对振幅的行为及其对热电系数的贡献。根据我们的Seebeck系数的结果，我们预测，奇数频率旋转曲线库珀对比传统的旋转单琴均匀甚至频率对，在增强连接点的热电上，尤其是混合旋转三胞胎配对是有利的。我们在热电学绩效图上的结果表明，当超导率由奇数频率配对支配时，铁磁/超导体连接是非常好的热电系统。
We explore the role of proximity-induced odd-frequency pairing in the thermoelectricity of a ferromagnet when coupled to a conventional $s$-wave spin-singlet superconductor through a spin-active interface. By varying both the polarization and its direction in the ferromagnet and the interfacial spin-orbit interaction strength, we analyze the behavior of all proximity-induced pair amplitudes in the ferromagnet and their contributions to the thermoelectric coefficients. Based on our results for the Seebeck coefficient, we predict that odd-frequency spin-triplet Cooper pairs are much efficient than the conventional spin-singlet even-frequency pairs in enhancing thermoelectricity of the junction, especially mixed-spin triplet pairing is favorable. Our results on the thermoelectric figure of merit show that ferromagnet/superconductor junctions are very good thermoelectric systems when superconductivity is dominated by odd-frequency pairing.
