论文摘要
在这项工作中，我们研究了量子拓扑计量计的电导和当前相关性能，该量子拓扑仪由QD组成，该QD耦合到限制在1D拓扑超导体环纳米线的两端的两个Majorana结合状态（MBS）。我们在其拓扑非微不足道和微不足道的阶段分析环，以表明隧道电导，射击噪声和Fano因子具有独特的特征，以区分MBS的标志。我们通过利用量子拓扑干涉仪与在直拓制超导体线构型中有效耦合到单个Majorana状态的点之间的对应关系来增强我们的发现。我们表明，除了特征性的零偏置电导$ e^{2} /2H $和已经知道的射击噪声功能外，Fano因子还提供了重要的信息来区分MBSS的存在。
In this work, we investigate the conductance and current correlations properties of a quantum topological inteferometer consisting of a QD coupled to two Majorana Bound States (MBSs) confined at both ends of a 1D topological superconductor ring nanowire. We analyze the ring in its topological non trivial and trivial phases to show that the tunneling conductance, shot noise and fano factor present unique characteristics to distinguish the hallmark of MBSs. We reinforce our findings by taking advantage of the correspondence between the quantum topological interferometer and a dot effectively coupled to a single Majorana state in a straight topological superconductor wire configuration. We show that, besides the characteristic zero-bias conductance $e^{2} /2h$ and the already known shot noise features, the Fano factor provides significant information to distinguish the MBSs presence.
