论文摘要
我们检查了一个双量子点系统的传输性能，该系统耦合到托管纳米线的末端，其末端寄主纳米线，并将中央量子点附着在左右导线上。我们专注于借助数值重新归一化方法计算的状态局部密度和线性电导的行为，以描述MajoraNA耦合对近多相关性诱导的低温传输特性的影响。特别是，我们表明，系统中主要的主要粒子的存在会影响旋转和旋转的传输通道，从而影响与第一阶段和第二阶段的围栏温度相关的能量尺度，并影响了系统的低能量行为。
We examine the transport properties of a double quantum dot system coupled to a topological superconducting nanowire hosting Majorana quasiparticles at its ends, with the central quantum dot attached to the left and right leads. We focus on the behavior of the local density of states and the linear conductance, calculated with the aid of the numerical renormalization group method, to describe the influence of the Majorana coupling on the low-temperature transport properties induced by the Kondo correlations. In particular, we show that the presence of Majorana quasiparticles in the system affects both the spin-up and spin-down transport channels, affecting the energy scales associated with the first-stage and second-stage Kondo temperatures, respectively, and modifying the low-energy behavior of the system.
