Majorana Modes (IMAGE)
Caption
Comparison of a system without an impurity and one with a local impurity at the centre of the vortex. The distribution of the wave function of a low-energy bound state in the non-topological regime (B/F): in the absence of an impurity, the state is more strongly localised at the vortex core, whereas in the presence of an impurity, its profile is significantly modified. The spatial distribution of the modulus of the MZM wave function in the topological regime (C/G): although the impurity alters the spatial profile, the state remains localised in the vortex region. The average local density of states at the vortex centre for both topological and conventional regimes (D/H): without an impurity, low-energy signals strongly overlap, while in the presence of an impurity, the differences between them become more pronounced.
