Both theoretical and experimental studies of topological phases in non-Hermitian systems
have made a remarkable progress in the last few years of research. In this article, we review …

The exploration of quantum‐inspired symmetries in optical and photonic systems has
witnessed immense research interest both fundamentally and technologically in a wide …

We address the conditions required for a Z topological classification in the most general form
of the non-Hermitian Su-Schrieffer-Heeger (SSH) model. Any chirally symmetric SSH model …

We investigate dissipative extensions of the Su-Schrieffer-Heeger model with regard to
different approaches of modeling dissipation. In doing so, we use two distinct frameworks to …

Topological edge states appear at the interface of two topologically distinct Hermitian
insulators. We study the extension of this idea to non-Hermitian systems. We consider PT …

We consider a non-Hermitian generalization of the Kitaev model and study the existence of
stable Majorana zero energy modes. We show that they exist in the limit of zero chemical …

A two component nonlocal vector nonlinear Schrödinger equation (VNLSE) is considered
with a self-induced parity-time-symmetric potential. It is shown that the system possess a Lax …

We study PT symmetry protected topological phase in non-Hermitian 1D and 2D systems.
We show that topological phase exist in non-Hermitian PT symmetric systems for both …

We investigate the boundary condition dependence of non-Hermitian topological systems.
We consider a complex extension of the Su-Schrieffer-Heeger model. We discuss that …
