Exceptional points (EPs) arising in non-Hermitian systems have led to a variety of intriguing
wave phenomena, and have been attracting increased interest in various physical platforms …

All-dielectric metamaterials and metasurfaces have been demonstrated as ideal platforms to
manipulate electromagnetic waves and enhance light–matter interaction. Analogous to …

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 …

As a fundamental optical approach to interferometry, Sagnac interference has been widely
used for reflection manipulation, precision measurements, and spectral engineering in …

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

Recent years have seen remarkable development in open quantum systems effectively
described by non-Hermitian Hamiltonians. A unique feature of non-Hermitian topological …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Let there be light–to change the world we want to be! Over the past several decades, and
ever since the birth of the first laser, mankind has witnessed the development of the science …

Dissipation is a general feature of non-Hermitian systems. But rather than being an
unavoidable nuisance, non-Hermiticity can be precisely controlled and hence used for …

A unique feature of non-Hermitian systems is the skin effect, which is the extreme sensitivity
to the boundary conditions. Here, we reveal that the skin effect originates from intrinsic non …
