检测Majorana束缚态

Detecting Majorana bound states

Colin Benjamin, Jiannis K. Pachos

摘要:

我们提出了一套如何探测拓扑绝缘体诱导的Majorana束缚态的干涉方法。这些状态的存在可以通过作为磁通量和/或电压的函数的电导振荡来容易地确定。我们研究的系统中存在和不存在的马约拉纳束缚态,并观察到显着不同的行为。重要的是,我们表明,耦合的马约拉纳束缚态的存在下,可以在没有任何外部磁场诱导持续电流。

英文摘要:

We propose a set of interferometric methods on how to detect Majorana bound states induced by a topological insulator. The existence of these states can be easily determined by the conductance oscillations as function of magnetic flux and/or electric voltage. We study the system in the presence and absence of Majorana bound states and observe strikingly different behaviors. Importantly, we show that the presence of coupled Majorana bound states can induce a persistent current in absence of any external magnetic field.
