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 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 …

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

A unique feature of non-Hermitian (NH) systems is the NH skin effect, ie, the edge
localization of an extensive number of bulk-band eigenstates in a lattice with open or semi …

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 …

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 …

Non-Hermitian systems exhibit nontrivial band topology and a strong sensitivity of the
energy spectrum on the boundary conditions. Remarkably, a macroscopic number of bulk …

The explorations of non-Hermiticity have been devoted to investigate the disorder-induced
many-body localization (MBL). However, the sensitivity of the spatial boundary conditions …
