报告摘要：

According to the picture of the BdG approach, the ideal zero-energy Majorana bound states (MBSs) would switch off the coupling between the left and right MZMs, leading thus to vanishing cross correlations. In this talk, we reconsider this problem by applying the occupation-number-state based master equation approach and in particular in the presence of finite charging energy of the Majorana island. The charging energy can eliminate the degeneracy of the teleportation and the Andreev reflection channels. This allows us to reveal the cross correlation mediated by the nonlocal MZMs. We analyze the noise power spectrum and carry out understanding in terms of charge transfer dynamics picture.
