Abstract

We study the optical properties of a hybrid device composed by a quantum dot (QD) resonantly coupled to a photonic mode of an optical microcavity and a Majorana nanowire: a topological superconducting segment hosting Majorana bound states (MBSs) at the opposite ends. In the regime of strong light-matter coupling, it is demonstrated that the leakage of the Majorana mode into the QD opens new optical transitions between polaritonic states formed due to hybridization of material excitation with cavity photons, which leads to the reshaping of the Jaynes-Cummings ladder and can lead to the formation of a robust single peak at cavity eigenfrequency in the emission spectrum. Moreover, weak satellite peaks in the low- and high-frequency regions are revealed for the distinct cases of highly isolated MBSs, overlapped MBSs, and MBSs not well localized at the nanowire ends.
