参数电子抽运的最新进展(英文)

Recent Progress in the Parametric Pumping

评述含时散射矩阵方法和非平衡格林函数方法的参数电子抽运的一般理论 ,分析论证了这两种方法的计算公式之间的联系 ,指出该普适理论在对量子抽运行为的预言上与绝热近似理论不同 .

In this paper, we give an overview of the general theory of parametric pumping within the framework of time dependent scattering matrix theory and the nonequilibrium Green's function theory. The relationship between these two basic formalisms is also discussed. The behavior of quantum pump predicted by the general theory can be very different from the adiabatic theory.
