论文摘要
我们研究了主要结合状态对量子电阻器电路的交流响应的影响，该电容器由拓扑超导电线组成，该电线的两端分别与铅耦合到铅和无旋转量子点。发现在电线的两端形成的主要状态可完全抑制或大大增强耗散状态，这取决于两种Majorana模式和/或点水平之间重叠的强度。我们将系统的放松抗性和量子电容与非Majorana对应物的抗性能力进行了比较，以发现Majoraana状态对AC响应的影响是真实的，并且不能在普通的Fermonic系统中再现。
We investigate the effects of Majorana bound states on the ac response of a quantum resistor-capacitor circuit which is composed of a topological superconducting wire whose two ends are tunnel-coupled to a lead and a spinless quantum dot, respectively. The Majorana states formed at the two ends of the wire are found to suppress completely or enhance greatly the dissipation, depending on the strength of the overlap between two Majorana modes and/or the dot level. We compare the relaxation resistance and the quantum capacitance of the system with those of non-Majorana counterparts to find that the effects of the Majorana state on the ac response are genuine and cannot be reproduced in ordinary fermonic systems.
