Transport properties of Floquet Majorana modes and Floquet quasi-Majorana modes

We numerically investigate the properties of Floquet Majorana zero modes (FMZMs) and partially-separated Floquet quasi-Majorana modes (FQMMs) in a realistic Floquet topological superconductor. The model consists of a periodically driven nanowire proximitized to an s-wave superconductor, whose dissipative nature needs to be taken into account due to the periodic drive [1]. We study the spectrum of the driven nanowire in the two phases, topological and trivial, as well as the transport properties of the FMZMs and FQMMs when coupled to a quantum dot and external leads.
