摘要:

研究了零磁场下超导-半导体混合纳米线中的端-端关联束缚态。从每个线端独立地识别子间隙电导中的峰,并且计算交叉关联函数,该交叉关联函数对端到端的重合进行计数,对数千个子间隙特征进行平均。短的$300~\mathrm{nm}$器件中的强相关性在长的$900~\mathrm{nm}$器件中被减小四倍。此外,亚间隙电导分布进行了研究,并确定基于其互信息的左右分布之间的相关性。

英文摘要:

End-to-end correlated bound states are investigated in superconductor-semiconductor hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently identified from each wire end, and a cross-correlation function is computed that counts end-to-end coincidences, averaging over thousands of subgap features. Strong correlations in a short, $300~\mathrm{nm}$ device are reduced by a factor of four in a long, $900~\mathrm{nm}$ device. In addition, subgap conductance distributions are investigated, and correlations between the left and right distributions are identified based on their mutual information.
