In this Letter we suggest a realization of the SU(N) Kondo effect, using quantum dots at strong magnetic field. We propose using edge states of the quantum Hall effect as pseudospin that interact with multiple quantum dots structures. In the suggested realization one can access each pseudospin separately and hence may perform a set of experiments that were impossible until now. We focus on the realization of SU(2) and SU(3) Kondo effects and find in the unitary limit a conductivity of 3/4 quantum conductance in the SU(3) case.
在这封信中，我们建议使用强磁场下的量子点来实现 SU(N) 近藤效应。我们提出使用量子霍尔效应的边缘态作为与多个量子点结构相互作用的赝自旋。在所建议的实现中，可以分别访问每个赝自旋，从而可以进行一组迄今为止不可能进行的实验。我们专注于 SU(2) 和 SU(3) 近藤效应的实现，并在幺正极限下发现 SU(3) 情况下的电导率为 3/4 量子电导率。
