从理论上研究了耦合量子点与电子库（电极）系统的电子输运。这些考虑仅限于由两个和三个量子点组成的系统。主要关注的是各种干扰效应，包括近藤现象。这些效应中的一些类似于原子物理学中已知的类似现象，例如迪凯和法诺共振。利用非平衡绿色函数方法和从玻色子平均场理论计算了体系的光谱性质以及线性和非线性电导等输运特性。
Electronic transport through systems of coupled quantum dots attached to electron reservoirs (electrodes) is investigated theoretically. The considerations are restricted to systems consisting of two and three quantum dots. The main attention is paid to various interference effects, including the Kondo phenomenon. Some of these effects resemble similar phenomena known in atomic physics, like for instance Dicke and Fano resonances. Spectral properties as well as transport characteristics such as linear and nonlinear conductance were calculated using the nonequilibrium Green function formalism and the slave-boson mean field theory.
