Large efforts have been placed on topological phases in non-Hermitian systems, where the appearance of exceptional points (EPs) and nontrivial Berry phase gather great interest. This study proposes an exhaustive classification framework for EPs, which connects eigenstate switching and Berry phase and ...
However, few practical approach exists for the eigenanalysis of non-Hermintian ones, such as arising from modern power systems. The main difficulty lies in the fact that, as the eigenvector matrix of a general matrix can be non-unitary, solving a general eigenvalue problem is inherently ...

We review the current understanding of the role of topology in non-Hermitian (NH) systems, and its far-reaching physical consequences observable in a range of dissipative settings. In particular, we elucidate how the paramount and genuinely NH concept of exceptional degeneracies, at which both eige...

Non-Hermitian systems exhibit striking exceptions from the paradigmatic bulk-boundary correspondence, including the failure of bulk Bloch band invariants in predicting boundary states and the (dis)appearance of boundary states at parameter values far from those corresponding to gap closings in periodic sys...

We explore the unconventional wave scattering properties of non-Hermitian systems in which gain and loss are modulated in a time-periodic manner. We show that properly designed non-Hermitian time-Floquet systems are capable of non-reciprocal operations in the frequency domain, which can be exploited...
