论文摘要
我们预测在正常的金属 - 渗透器连接处发生奇数频率相等的旋转三个相关性。该结果很重要，因为相等的旋转三个相关性与无耗散纯自旋电流的存在相关。在正常金属螺旋体连接的界面上插入自旋飞机，激发了相等的自旋 - 三个相关性。在没有奇数频率混合旋转三个相关性的情况下，奇数频率相等的旋转三个相关性的存在是这项工作的主要带回家信息。它与界面处的状态状态的局部磁化密度和自旋偏振密度很好地分配。当我们将正常的金属旋转脚钳连接与其他杂交连接处进行比较时，自旋翼散射与获得的结果的重要性显现出来，在这些杂交连接中仅存在旋转混合或旋转混合和自旋窗户散射。
We predict the occurrence of odd frequency equal-spin-triplet correlations at a normal metal-superconductor junction. This result is significant because equal-spin-triplet correlations are associated with the presence of dissipation-less pure spin current. Inserting a spin-flipper at the interface of a normal metal-superconductor junction excites equal-spin-triplet correlations. The existence of odd frequency equal-spin-triplet correlations in absence of odd frequency mixed spin-triplet correlations is the main take-home message of this work. It tallies well with the measured local magnetization density of states and spin-polarized local density of states at the interface. The importance of spin-flip scattering to the obtained results is manifest when we compare our normal metal-spin flipper-superconductor junction to other hybrid junctions where either only spin mixing or both spin mixing and spin-flip scattering are present.
