AI中文摘要：
我们预测在具有平行邻近诱导交换场的超导纳米收缩结电极中，存在相干多重安德烈夫反射机制。亚谐波间隙结构由电极自旋分辨谱的重构控制，而非BCS间隙边缘的刚性位移。这产生了由外间隙边缘与移动的交换诱导态密度奇点之间的间隔决定的分裂和重新分布的异常。该效应在通道透明度平均后依然存在，为自旋分辨邻近态提供了直接的输运探测手段。
英文摘要：
We predict a coherent multiple Andreev reflection regime in superconducting nanoconstrictions with parallel proximity-induced exchange fields in the electrodes. The subharmonic gap structure is controlled by reconstruction of the spin-resolved electrode spectra, rather than by a rigid displacement of BCS gap edges. This produces split and redistributed anomalies governed by the interval between the outer gap edge and a shifted exchange induced density of states singularity. The effect survives channel transparency averaging and provides a direct transport probe of spin-resolved proximity states.
