Both theoretical and experimental studies of topological phases in non-Hermitian systems
have made a remarkable progress in the last few years of research. In this article, we review …

Non-Hermitian systems exhibit striking exceptions from the paradigmatic bulk-boundary
correspondence, including the failure of bulk Bloch band invariants in predicting boundary …

Asymmetric coupling amplitudes effectively create an imaginary gauge field, which induces
a non-Hermitian Aharonov-Bohm (AB) effect. Nonzero imaginary magnetic flux invalidates …

Non-Hermitian (NH) Hamiltonians have become an important asset for the effective
description of various physical systems that are subject to dissipation. Motivated by recent …

We propose an anti-parity-time (anti-PT) symmetric non-Hermitian Su-Schrieffer-Heeger
(SSH) model, where the large non-Hermiticity constructively creates nontrivial topology and …

The generic nature of band touching points in three-dimensional band structures is at the
heart of the rich phenomenology, topological stability, and novel Fermi arc surface states …

We investigate the localization and topological transitions in a one-dimensional (interacting)
non-Hermitian quasiperiodic lattice, which is described by a generalized Aubry-André …

A non-Hermitian topological insulator with a real spectrum is interesting in the theory of non-
Hermitian extension of topological systems. We find an experimentally realizable example of …

The interplay among topology, disorder, and non-Hermiticity can induce some exotic
topological and localization phenomena. Here we investigate this interplay in a two …

Topological pumping of edge states in finite crystals or quasicrystals with nontrivial
topological phases provides a powerful means for robust excitation transfer. In most …
