Zero-energy pinning of topologically trivial bound states in multiband semiconductor-superconductor nanowires
Zero-energy pinning of topologically trivial bound states in multiband semiconductor-superconductor nanowires
Recent tunneling conductance measurements on semiconductor-superconductor nanowires find zero-bias peaks to be ubiquitous across wide ranges of chemical potential and Zeeman energy J. Chen et al., Phys. Rev. Lett. 123, 107703 (2019). Motivated by this, we demonstrate that topologically trivial Andreev abound states (ABSs) pinned near zero energy are produced …
