Majorana molecules and their spectral fingerprints

Interaction induced hybridization of Majorana zero-modes in a coupled quantum-dot hybrid-nanowire system

“…Strong disorder can also lead to such trivial ZBPs [37,39]. In order to distinguish between the ZBPs stemming from authentic topological MZMs and those arising from trivial zero-energy ABSs, a plethora of strategies have been proposed [30,[40][41][42][43][44][45][46][47]. Among them, we draw attention for those ones which suggest experimental verification of "how topological" are the MZMs, either by means of the measurement of so-called topological quality factor [41] or degree of Majorana nonlocality.…”
