相互作用量子线中双势垒输运的干涉

Interference in transport through double barriers in interacting quantum wires

Shaoqing Wang, Liling Zhou, Zhao Yang Zeng

摘要:

我们研究了通过双势垒结构的后向散射电流在相互作用量子线中的干涉效应。在强相互作用和弱相互作用情况下,背散射电流随外加电压的变化呈现出不同的振荡和标度特性,这取决于相互作用的强度和势垒的位置。然而,在这两种情况下,由于双势垒的存在,后向散射电流的振荡行为主要由量子力学干涉决定。

英文摘要:

We investigate interference effects of the backscattering current through a double-barrier structure in an interacting quantum wire attached to noninteracting leads. Depending on the interaction strength and the location of the barriers, the backscattering current exhibits different oscillation and scaling characteristics with the applied voltage in the strong and weak interaction cases. However, in both cases, the oscillation behaviors of the backscattering current are mainly determined by the quantum mechanical interference due to the existence of the double barriers.
