While several properties unique to non-Hermitian topological systems were uncovered, the fundamental role of symmetry in non-Hermitian physics has yet to be fully understood, and it has remained unclear how symmetry protects non-Hermitian topological phases. Here we show that two fundamental anti-...
Non-Hermitian topology plays a pivotal role in physical science and technology, exerting a profound impact across various scientific disciplines. Recently, the interplay between topological physics and nonlinear synchronization has aroused a great intere

non-Hermitian skin effect (NHSE) is a phenomenon in physics where the eigenstate is localized to the boundary or corner of one side of the system [1,2]. Unlike conventional topological states, the NHSE arises from non-Hermitian parameters such as gain and loss, enabling unique control over ...
In particular, we discuss rich and unique phenomena found therein, such as unidirectional invisibility, enhanced sensitivity, topological energy transfer, coherent perfect absorption, single-mode lasing, and robust biological transport. We then explain in detail how non-Hermitian operators emerge as an ...

Manipulating topological invariants is possible by modifying the global properties of optical devices to alter their band structures. This could be achieved by statically altering devices or dynamically reconfiguring devices with considerably different g
