摘要

我们研究了由两个（可能不同）Sachdev–Ye–Kitaev（SYK）模型描述的一对量子点之间的耗散隧道结表示的单电子晶体管（SET）的行为。讨论了软集体电荷和能量模式对电荷传输的综合影响，以及库仑阻塞和涌现的近藤共振的竞争效应，这些都可能导致系统电导的非单调行为。

One SYK single electron transistor

We study the behaviour of a single electron transistor (SET) represented by a dissipative tunnel junction between a pair of quantum dots described by two (possibly, different) Sachdev–Ye–Kitaev (SYK) models. A combined influence of the soft collective charge and energy modes on charge transport is discussed, alongside the competing effects of the Coulomb blockade and emergent Kondo resonances which might all conspire to result in a non-monotonic behaviour of the system’s conductance.
