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 …

The synergy between non-Hermitian concepts and topological ideas have led to very fruitful
activity in the recent years. Their interplay has resulted in a wide variety of new non …

Useful in the enhancement of light-matter interaction, localization of light is at the heart of
photonics studies. Different approaches have been proposed to localize light, including …

The non-Hermitian skin effect (NHSE), which involves an extensive number of bulk modes
collapsing to open boundaries as skin modes, unveils a variety of unprecedented …

Photonic crystals (PhCs) have emerged as a popular platform for realizing various
topological phases due to their flexibility and potential for device applications. In this article …

In the band theory for non-Hermitian systems, the energy eigenvalues, which are complex,
can exhibit nontrivial topology which is not present in Hermitian systems. In one dimension …

In some non-Hermitian systems, the eigenstates in the bulk are localized at the boundaries
of the systems. This is called the non-Hermitian skin effect, and it has been studied mostly in …
