The current understanding of the role of topology in non-Hermitian (NH) systems and its far-
reaching physical consequences observable in a range of dissipative settings are reviewed …

Non-Hermitian photonics and topological photonics, as new research fields in optics, have
attracted much attention in recent years, accompanying by a great deal of new physical …

One of the unique features of non-Hermitian Hamiltonians is the non-Hermitian skin effect,
namely, that the eigenstates are exponentially localized at the boundary of the system. For …

The topology of non-Hermitian systems is drastically shaped by the non-Hermitian skin
effect, which leads to the generalized bulk-boundary correspondence and non-Bloch band …

Exceptional points are universal level degeneracies induced by non-Hermiticity. Whereas
past decades witnessed their new physics, the unified understanding has yet to be obtained …

Higher-order topology realizes topologically robust corner modes as a manifestation of
nontriviality. We theoretically propose non-Hermitian skin effects which stem from the …

We analyze the impacts of crystalline symmetry on non-Hermitian skin effects. Focusing on
mirror symmetry, we propose another type of skin effect, a mirror skin effect, which results in …

We classify topological defects in non-Hermitian systems with point, real, and imaginary
gaps for all the Bernard-LeClair classes or generalized Bernard-LeClair classes in all …

In this Letter, we study three-dimensional non-Hermitian higher-order Dirac semimetals
(NHHODSMs). Our focus is on C 4-symmetric non-Hermitian systems where we investigate …

Majorana edge modes are candidate elements of topological quantum computing. In this
paper, we propose a Floquet engineering approach to generate multiple non-Hermitian …
