Hermitian bulk–non-Hermitian boundary correspondence
Non-Hermitian band theory distinguishes between line gaps and point gaps. While point
gaps can give rise to intrinsic non-Hermitian band topology without Hermitian counterparts …

[HTML][HTML] Majorana bound states in semiconducting nanostructures
K Laubscher, J Klinovaja - Journal of Applied Physics, 2021 - pubs.aip.org
In this Tutorial, we give a pedagogical introduction to Majorana bound states (MBSs) arising
in semiconducting nanostructures. We start by briefly reviewing the well-known Kitaev chain …
