[HTML][HTML] Non-Hermitian extended midgap states and bound states in the continuum

M Zelenayova, EJ Bergholtz - Applied Physics Letters, 2024 - pubs.aip.org
We investigate anomalous localization phenomena in non-Hermitian systems by solving a
class of generalized Su–Schrieffer–Heeger/Rice–Mele models and by relating their …

On the non-hermitian Kitaev chain

E Ardonne, V Kurasov - arxiv preprint arxiv:2411.14776, 2024 - arxiv.org
We study the non-hermitian Kitaev chain model, for arbitrary complex parameters. In
particular, we give a concise characterisation of the curves of eigenvalues in the complex …
