Abstract

In this paper, we investigate the influence of Majorana bound states on the Fano–Rashba effect in a two-channel Fano–Anderson model. Employing Green's function formalism and the equation of motion method, we compute the transmission through the quantum dot and the density of states. Our analysis reveals that the Majorana bound states, localized at the ends of the topological superconductor nanowire, penetrate into the quantum dot and interact with the bound states in the continuum, thereby altering the interference pattern in the electronic transmission profile. Furthermore, we explore the robustness of the bound state in the continuum concerning its connection to Majorana bound states and the energy induced by the perpendicular component of the magnetic field. We posit that our findings contribute to a deeper comprehension of the Fano–Rashba effect in a two-channel quantum dot coupled to a topological superconducting nanowire. © 2025 Elsevier B.V.
