现有的散粒噪声计算研究表明,当两个电极之间的耦合能量为1时,由一对Majorana零模(MZM)连接的两个电极中电流之间的互相关消失。M → 0。出于MZM的非局部性的内在本质,我们重新审视这个重要的问题,并提出了一个实验方案来证明非零交叉相关性,即使在极限λ。M → 0。该方案采用Andreev过程相关的分支电路电流,理论上通过对总电流进行分解分析而获得,而在实际测量中可直接获得。对于不同的偏置电压设置,我们发现有趣的结果的负和正的相关性和进行简单的物理理解使用量子跳跃技术。重要的是,结合电导的零偏峰的证据,本文预测的非局域互相关有助于证实非局域MZM的存在。
Existing studies via shot noise calculation conclude that the cross correlation between the currents in the two leads connected by a pair of Majorana zero modes (MZMs) vanishes when their coupling energy ϵ. M → 0. Motivated by the intrinsic nature of nonlocality of the MZMs, we revisit this important problem and propose an experimental scheme to demonstrate the nonvanishing cross correlation even at the limit ϵ. M → 0. The proposed scheme employs the Andreev-process-associated branch circuit currents, which are theoretically obtained by applying a decomposition analysis for the total currents while are accessible directly in practical measurement. For different bias voltage setup, we find intriguing results of both negative and positive correlationsand carry out simple physical understanding using a quantum jump technique. Importantly, combining together with the evidence of the zero-bias-peak of conductance, the nonlocal cross correlation predicted in this work can help to confirm the existence of thenonlocalMZMs.
