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 …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

Beyond the scope of Hermitian physics, non-Hermiticity fundamentally changes the
topological band theory, leading to interesting phenomena, eg, non-Hermitian skin effect, as …

Topological band theory establishes a standardized framework for classifying different types
of topological matters. Recent investigations have shown that hyperbolic lattices in non …

The non-Hermitian skin effect (NHSE) in non-Hermitian lattice systems, associated with a
point gap on the complex energy plane, has attracted great theoretical and experimental …

From biological ecosystems to spin glasses, connectivity plays a crucial role in determining
the function, dynamics, and resiliency of a network. In the realm of non-Hermitian physics …

The discovery of non-Hermitian skin effect (NHSE) has opened an exciting direction for
unveiling unusual physics and phenomena in non-Hermitian system. Despite notable …

Dimensionality plays a fundamental role in the classification of novel phases and their
responses. In generic lattices of 2D and beyond, however, we found that non-Hermitian …

We revisit the fate of the skin modes in many-body non-Hermitian fermionic systems.
Contrary to the single-particle case, the many-body ground state cannot exhibit an …
