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 …

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 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 …

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 …

Non-Hermiticity gives rise to unique topological phases that have no counterparts in
Hermitian systems. Such intrinsic non-Hermitian topological phases appear even in one …

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 …

Non-Hermitian band theory distinguishes between line gaps and point gaps. While point
gaps can give rise to intrinsic non-Hermitian band topology without Hermitian counterparts …

Non-Hermitian systems show a non-Hermitian skin effect, where the bulk states are
localized at a boundary of the systems with open boundary conditions. In this paper, we …

The non-Bloch band theory can describe energy bands in a one-dimensional (1D) non-
Hermitian system. On the other hand, whether the non-Bloch band theory can be extended …

Being motivated by intriguing phenomena, such as the breakdown of conventional bulk
boundary correspondence and the emergence of skin modes in the context of non-Hermitian …
