| contents | We study the phase diagram of a disordered Kitaev chain with long-range pairing when connected to two metallic leads exchanging particles with external Lindblad baths. We (i) monitor the subgap modes at increasing disorder, (ii) compute the current flowing across the system at a finite voltage bias between the baths, and (iii) study the normal single particle lead correlations across the chain. Throughout our derivation, we evidence the interplay between disorder and topology. In particular, we evidence the reentrant behavior of the massive, topological
phase at limited values of the disorder strength, similar to what happens in the short-range pairing
Kitaev model. Our results suggest the possibility of a disorder-induced direct transition between the massive and
the short-range topological phase of the long-range pairing Kitaev model. |
