论文摘要
我们报告了一项实验研究，该研究对超导铝线的非平衡准颗粒注射和超电流的综合作用。在低温下，我们观察到超电流诱导的能量耦合以及电荷不平衡与光谱分辨率。在高磁场上，在存在状态密度的采面部分裂的情况下，我们找到了额外的自旋依赖性耦合的证据，该耦合最近在理论上被预测。
We report on an experimental investigation of the combined effect of nonequilibrium quasiparticle injection and supercurrent in superconducting aluminum wires. At low temperature, we observe the supercurrent-induced coupling of energy and charge imbalance with spectral resolution. At high magnetic fields, in the presence of a Zeeman splitting of the density of states, we find evidence for an additional spin-dependent coupling which has been recently predicted theoretically.
