Influences of electron-phonon interaction on quantum transport through one quantum-dot system with side-coupled Majorana zero mode

摘要

We investigate the influences of the electron-phonon interaction on the transport properties of one quantum-dot system with a side-coupled Majorana zero mode (MZM). Our calculation results show that at the zero-temperature limit, the MZM-governed zero-bias conductance value can be magnified, dependent on the interplay between electron-phonon interaction and dot-MZM coupling. In the case of finite temperature, the electron-phonon interaction makes leading contributions to the suppression of the magnitude of zero-bias conductance, but the effect is different from the case of electron tunneling without MZM. We believe that this work can be helpful for understanding the signature of the MZM in electron transport through mesoscopic circuits. (C) 2020 Elsevier Inc. All rights reserved.
