Transport properties of Coulomb blockaded T-junctions hosting Majorana bound states — •Johan Ekström1, Patrik Recher2, and Thomas Schmidt1 — 1Physics and Materials Science Research Unit, University of Luxembourg, Luxembourg — 2Institute for Mathematical Physics, TU Braunschweig, 38106 Braunschweig, Germany
We study electron transport through a T-shaped nanowire junction hosting Majorana bound states (MBS). When the T-junction is in the topologically nontrivial regime it hosts three MBS at the ends of the wires and one MBS localized at the crossing point of the junction. For finite wire length, the MBS localized at the ends overlap with the MBS at the crossing point. It was found previously that such a setup can give rise to exotic transport processes such as double crossed Andreev reflections. In this work, we investigate the effect of Coulomb blockade and study the different transport processes due to the coupling between the MBS using a master equation in the sequential tunneling regime.
