Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

Skin effect, experimentally discovered in one dimension, describes the physical
phenomenon that on an open chain, an extensive number of eigenstates of a non-Hermitian …

Non-Hermitian matrices are ubiquitous in the description of nature ranging from classical
dissipative systems, including optical, electrical, and mechanical metamaterials, to scattering …

Non-Hermitian systems generically have complex energies, which may host topological
structures, such as links or knots. While there has been great progress in experimentally …

In this Letter, we introduce the concept of dynamical degeneracy splitting to describe the
anisotropic decay behaviors in non-Hermitian systems. We demonstrate that systems with …

We study the geometric response of three-dimensional non-Hermitian crystalline systems
with nontrivial point-gap topology. For systems with fourfold rotation symmetry, we show that …

Exotic quantum phases and phase transition in the strongly interacting Dirac systems have
attracted tremendous interests. On the other hand, non-Hermitian physics, usually …

The non-Hermitian skin effect is a distinctive phenomenon in non-Hermitian systems, which
manifests as the anomalous localization of bulk states at the boundary. To understand the …

Strong, non-perturbative interactions often lead to new exciting physics, as epitomized by
emergent anyons from the Fractional Quantum hall effect. Within the actively investigated …

Non-Hermitian skin effects and exceptional points are topological phenomena characterized
by integer winding numbers. In this study, we give methods to theoretically detect skin effects …
