Abstract
- We investigate the Andreev reflection in the heterostructure formed by the indirect coupling between the metallic lead and Majorana zero mode (MZM) via one quantum dot which suffers from the electron-phonon interaction. Our calculation results show that at the zero-temperature limit, the MZM-governed zero-bias conductance value is independent of the electron-phonon interaction. However at finite temperature, the electron-phonon interaction exacerbates the suppression of the magnitude of zero-bias conductance. We believe that the results in this work can help to further differentiate the signature of the MZM in the Andreev reflection process.
