Along similar lines, coupled non-Hermitian systems have provided yet additional degrees of freedom to obtain better sensors via higher-order exceptional points. Quite recently, a new class of non-Hermitian systems, known as non-Hermitian topological sensors (NTOS) has been theoretically proposed. ...

A mathematical structure composed of three topological spaces (total space, base space and fibres) and a projection map. The fibres adhere to the base space and their product space further gives the total space by the projection map, a continuous surjection satisfying a local triviality condition...
Applications of non-Hermitian photonics toward device applications, such as sensors, lasers, and amplifiers Synergistic topics in heat and sound 客座编辑: Liang Feng(冯亮), University of Pennsylvania Li Ge, CUNY College of Staten Island Minghui L...
improving the efficiency in asymmetric transmission based on EPs, optical isolators in nonlinear EP systems and novel concepts to implement EPs in topological photonics. We also discuss the constraints and limitations of the applications relying on EPs, and offer parting thoughts about promising ways to...

In particular, the square root dependence of the eigenvalue splitting on different design parameters, exhibited by 2 × 2 non-Hermitian Hamiltonian matrices at the exceptional point, paved the way to the integration of high-performance sensors. The square root dependence of the eigenfrequencies on ...
Besides establishing a paradigmatic case to break the incompatibility of the LCTs and the TCTs in non‐Hermitian systems, the both availabilities of the sensitive critical feature and the robust topological feature can also provide more potential for designing quantum devices orsensors. 展开 关键词:...
