利用一般的定性论证和定量的从玻色子平均场理论研究了两个串联量子点的电导。结果表明，电导的测量可以探索双杂质安德森模型的相图。近藤效应和点间磁交换之间的竞争导致电导作为栅电压的函数的两个平台结构和电导与点间隧穿的两个或三个峰结构。[S0031-9007（99）09017-1]
The conductance through two quantum dots in series is studied using general qualitative arguments and quantitative slave-boson mean-field theory. It is demonstrated that measurements of the conductance can explore the phase diagram of the two-impurity Anderson model. Competition between the Kondo effect and the interdot magnetic exchange leads to a two-plateau structure in the conductance as a function to the gate voltage and a two or three peak structure in the conductance versus interdot tunneling.
