Trivial Andreev band mimicking topological bulk gap reopening in the non-local conductance of long Rashba nanowires
Richard Hess, Henry F. Legg, Daniel Loss +1
We consider a one-dimensional Rashba nanowire in which multiple Andreev bound states in the bulk of the nanowire form an Andreev band. We show that, under certain circumstances, th…

Prevalence of trivial zero-energy sub-gap states in non-uniform helical spin chains on the surface of superconductors
Richard Hess, Henry F. Legg, Daniel Loss +1
Helical spin chains, consisting of magnetic (ad-)atoms, on the surface of bulk superconductors are predicted to host Majorana bound states (MBSs) at the ends of the chain. Here, we…
