Coupling between Majorana bound state and quantum dot mediated by continuum

Systems which include Majorana-like zero-energy excitations are gaining great deal of attention because their interesting properties. For instance, because of their non-Abelian statistics they are potentially useful for quantum computation implementations. Among other systems, they are predicted to be found bound to the end of a topological superconductor nanowire. When the MBS is connected to a quantum dot (QD), unique features are observed at zero-energy due to the leakage of the MBS into the QD. In this work we consider a single level QD and an MBS placed at the end of a topological nanowire. Both are coupled to the continuum and does not have a direct connection between them. We addressed the behavior of Coulomb blockade and Kondo effect in the QD due to the presence of MBS in the continuum. By employing a Green's function formalism via equation of motion procedure we are able to calculate the relevant physical quantities. Our results show that the leakage of the MBS into continuum state can alter the either the Kondo physics of the system. We believe that our findings could be useful to establish new measurables features in MBS-QD systems.
