论文摘要
Andreev分子是一个紧密间隔的超导弱环节的系统，可容纳重叠的Andreev结合状态。最近的理论建议考虑了具有单个传导通道的一维Andreev分子。在这里，我们应用散射形式主义并将分析扩展到多个传导通道，这是在外延超导体/半导体弱环节中遇到的情况。我们获得了多通道结合的状态能谱，并量化了微观非本地过程的贡献，导致形成Andreev分子。
An Andreev molecule is a system of closely spaced superconducting weak links accommodating overlapping Andreev Bound States. Recent theoretical proposals have considered one-dimensional Andreev molecules with a single conduction channel. Here we apply the scattering formalism and extend the analysis to multiple conduction channels, a situation encountered in epitaxial superconductor/semiconductor weak links. We obtain the multi-channel bound state energy spectrum and quantify the contribution of the microscopic non-local processes leading to the formation of Andreev molecules.
