Non-Hermitian theory is a theoretical framework used to describe open systems. It offers a
powerful tool in the characterization of both the intrinsic degrees of freedom of a system and …

This article reviews recent developments in the non-Hermitian skin effect (NHSE),
particularly on its rich interplay with topology. The review starts off with a pedagogical …

The combination of broken Hermiticity and band topology in physical systems unveils a
novel bound state dubbed as the non-Hermitian skin effect (NHSE). Active control that …

Exceptional points and skin effect, as the two distinct hallmark features unique to the non-
Hermitian physics, have each attracted enormous interests. Recent theoretical works reveal …

The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

From protein motifs to black holes, topological solitons are pervasive nonlinear excitations
that are robust and can be driven by external fields. So far, existing driving mechanisms all …

Exceptional point (EP) has been captivated as a concept of interpreting eigenvalue
degeneracy and eigenstate exchange in non-Hermitian physics. The chirality in the vicinity …

Acoustic resonances in open systems, which are usually associated with resonant modes
characterized by complex eigenfrequencies, play a fundamental role in manipulating …

The non-Hermitian skin effect dramatically reshapes the energy bands of non-Hermitian
systems, meaning that the usual Bloch band theory is fundamentally inadequate as their …

Topological effects in photonic non-Hermitian systems have recently led to extraordinary
discoveries including nonreciprocal lasing, topological insulator lasers, and topological …
