金属引线与超导引线耦合量子点中的Fano型干涉

Fano-type interference in quantum dots coupled between metallic and superconducting leads

J. Baranski, T. Domanski

摘要:

分析了T形双量子点与各向同性超导体和金属铅耦合时,电荷流中出现的量子干涉效应。由于邻近效应,量子点中存在一对电子对,这种电子对对非平衡电荷输运有着深刻的影响,特别是在|eV| < Delta的亚带隙区域。我们讨论了在什么条件下的Fano型线型可能会出现在这样的Andreev电导,并考虑可能的相互作用与强相关效应。

英文摘要:

We analyze the quantum interference effects appearing in the charge current through the double quantum dots coupled in T-shape configuration to an isotropic superconductor and metallic lead. Owing to proximity effect the quantum dots inherit a pairing which has the profound influence on nonequilibrium charge transport, especially in the subgap regime |eV| < Delta. We discuss under what conditions the Fano-type lineshapes might appear in such Andreev conductance and consider a possible interplay with the strong correlation effects.
