论文摘要
我们研究了在面积内磁场存在下应用的直流电压偏置下的平面约瑟夫森连接。在调整跨交界处的偏置电压后，$ v _ {\ rm j} $，显示结的两端被证明同时托管$ 0 $ - 和$π$ -MAJORANA模式。这些模式可以使用扫描隧道 - 微镜测量或通过谐振的Andreev Tunneling从铅耦合到连接点进行探测。尽管这些模式大多与连接点的末端结合，但它们可以通过吸收或发射光子来与散装杂交。我们在数值和分析上分析了这一过程，表明在典型的实验条件下它可以忽略不计。 $ 0 $ - 和$π$ -Majorana状态的运输签名证明对中度疾病是可靠的。
We study a planar Josephson junction under an applied DC voltage bias in the presence of an in-plane magnetic field. Upon tuning the bias voltage across the junction, $V_{\rm J}$, the two ends of the junction are shown to simultaneously host both $0$- and $π$-Majorana modes. These modes can be probed using either a Scanning-Tunneling-Microscopy measurement or through resonant Andreev tunneling from a lead coupled to the junction. While these modes are mostly bound to the junction's ends, they can hybridize with the bulk by absorbing or emitting photons. We analyze this process both numerically and analytically, demonstrating that it can become negligible under typical experimental conditions. Transport signatures of the $0$- and $π$-Majorana states are shown to be robust to moderate disorder.
