The past decades have witnessed the flourishing of non-Hermitian physics in non-
conservative systems, leading to unprecedented phenomena of unidirectional invisibility …

Topological photonics emerged as a novel route to engineer the flow of light. Topologically
protected photonic edge modes, which are supported at the perimeters of topologically …

Non-Hermitian systems reveal rich physics beyond the Hermitian regime, and have aroused
great interest. One remarkable physical phenomenon is the non-Hermitian skin effect …

One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect,
namely, that the eigenstates are exponentially localized at the boundary of the system. For …

The topology of non-Hermitian systems is drastically shaped by the non-Hermitian skin
effect, which leads to the generalized bulk-boundary correspondence and non-Bloch band …

Exceptional points (EPs) correspond to degeneracies of open systems. These are attracting
much interest in optics, optoelectronics, plasmonics, and condensed matter physics. In the …

The hallmark of symmetry-protected topological phases is the existence of anomalous
boundary states, which can only be realized with the corresponding bulk system. In this …

The search of topological states in non-Hermitian systems has gained a strong momentum
over the last two years climbing to the level of an emergent research front. In this perspective …

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 Aubry-André-Harper (AAH) model with a self-dual symmetry plays an important role in
studying the Anderson localization. Here we find a self-dual symmetry determining the …
