Fano resonaces in spinfull Majorana bound state - quantum dot hybrid system — •Alexander Schuray1 and Patrik Recher1,21Institut für Mathematische Physik, TU Braunschweig — 2Laboratory for Emerging Nanometrology Braunschweig

The emergence of Majorana bound states (MBS) as topologically protected zero energy modes in hybrid superconductor-semiconductor devices spark a lot of research activities in the last couple of years [1]. Recently, it was reported that these hybrid devices can be coupled to a quantum dot [2]. In devices in which MBS are coupled to a quantum dot (QD) on one side and a normal conducting lead on the other side Fano resonances arise. These resonances can be used to identify and quantify the couplings to the MBS [3]. Here, we want to present our recent research in which we extend our previous work on a spinless MBS-QD system [3] to the spinful case including Coulomb interaction on the QD on a mean field level. We use full counting statistics to calculate the transport properties and support our analytical findings by numerical calculations using Kwant [4].
