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

Non-Hermitian band structures have gained considerable attention due to the novel
phenomena not present in their Hermitian counterparts and their connection to various …

The last 20 years have witnessed growing impacts of the topological concept on the
branches of physics, including materials, electronics, photonics, and acoustics. Topology …

Bound states in the continuum (BICs) present a unique solution for eliminating radiation
loss. So far, most reported BICs are observed in transmission spectra, with only a few …

Non-Hermitian skin effect (NHSE), characterized by a majority of eigenstates localized at
open boundaries, is one of the most iconic phenomena in non-Hermitian lattice systems …

Exceptional points are complex branching singularities of non-Hermitian bands that have
lately attracted considerable interest, particularly in non-Hermitian photonics. In this article …

We introduce feedback-measurement technologies to achieve flexible control of Weyl points
and conduct the first experimental demonstration of Weyl type I-II transition in mechanical …

The introduction of non-Hermiticity into topological systems has led to a series of novel
physical phenomena and produced application prospects. Here, we combine non-Hermitian …

Absolute negative mobility (ANM) in nonequilibrium systems depicts the possibility of
particles propagating toward the opposite direction of an external force. We uncover in this …
