Filling-Sensitive Spectral Complexity from Hilbert-Space Holonomy in Fragmented Non-Hermitian Systems
Jiong-Hao Wang, Maria Zelenayova, Christopher Ekman +1
We show that Hilbert-space holonomy provides a geometric organizing principle for spectral reality in fragmented non-Hermitian many-body systems, complementary to conventional symm…

Quantum dynamical signatures of non-Hermitian boundary modes
Fan Yang, Maria Zelenayova, Paolo Molignini +1
The non-Hermitian bulk-boundary correspondence features an interplay between the non-Hermitian skin effect and anomalous boundary-mode behavior. Whereas the skin effect is known to…

Non-Hermitian extended midgap states and bound states in the continuum
Maria Zelenayova, Emil J. Bergholtz
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 provenance to…
