Interference of electronic waves undergoing Andreev reflection in diffusive conductors determines the energy profile of the conductance on the scale of the Thouless energy. A similar dependence exists in the current noise, but its behavior is known only in a few limiting cases. We consider a metallic diffusive wire connected to a superconducting reservoir through an interface characterized by an arbitrary distribution of channel transparencies. Within the quasiclassical theory for current fluctuations we provide a general expression for the energy dependence of the current noise.
在扩散导体中经历安德列夫反射的电子波的干涉决定了在 Thouless 能量尺度上电导的能量分布。电流噪声中也存在类似的依赖性，但其行为仅在少数极限情况下为人所知。我们考虑一根金属扩散线，它通过一个具有任意通道透明度分布特征的界面连接到一个超导库。在电流涨落的准经典理论范围内，我们给出了电流噪声能量依赖性的一般表达式。
