论文摘要
从理论上讲，我们通过将Majorana绑定状态（MBS）引入夫妇到主通道中的DOT，从而研究T形双量子点结构中的传输性能。发现侧耦合点控制着MBS对运输行为的影响。当其水平与能量零点一致时，MB对电导频谱的贡献很小。否则，根据MBS Inter-MBS耦合方式，线性电导会显示出显着变化。在Majorana零模式的情况下，当侧耦合点的水平从能量零点出发时，线性电导值在2H $上等于$ e^2 \。但是，一旦MBS耦合发挥作用，线性电导总是类似于MBS的情况。这些发现提供了有关量子点中MBS和电子状态之间相互作用的新信息。
We theoretically study the transport properties in the T-shaped double-quantum-dot structure, by introducing the Majorana bound state (MBS) to couple to the dot in the main channel. It is found that the side-coupled dot governs the effect of the MBS on the transport behavior. When its level is consistent with the energy zero point, the MBS contributes little to the conductance spectrum. Otherwise, the linear conductance exhibits notable changes according to the inter-MBS coupling manners. In the case of Majorana zero mode, the linear conductance value keeps equal to $e^2\over 2h$ when the level of the side-coupled dot departs from the energy zero point. However, the linear conductance is always analogous to the MBS-absent case once the inter-MBS coupling comes into play. These findings provide new information about the interplay between the MBSs and electron states in the quantum dots.
