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. ...
geometric-dependent non-Hermitian skin effects in high dimensions20,21,22,23,24, skin-topological modes25,26,27, the non-Hermitian morphing of midgap topological modes28, and the development of non-Hermitian topological sensors, which offer unprecedented sensitivity due to the amplification of boundar...
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...
This gap hinders the practical application of NHSE in advanced photonic devices, such as unidirectional waveguides or topological sensors, where precise control over corner-localized modes is essential[[17], [18], [19], [20], [21]]. Here, we propose a tandem deep learning framework to ...

The interplay between topology and dissipation can give rise to a wealth of new phenomena and pave the way for novel topological lasers, sensors, and other quantum devices. Along these lines, we propose here an optomechanical setup in which the concomitant presence of a spatially modulated ...
protected from internal perturbation of site-to-site couplings.Our demonstration of a non-Hermitian topological structure with an EP paves the way for the development of novel sensors that are not sensitive to internal manufacturing errors but are highly sensitive to changes in the external ...
Here, we propose theoretically and demonstrate experimentally an alternative class of sensors with superior performances based on exotic properties of high-order non-Hermitian topological physics. The frequency shift induced by perturbations for these sensors can show an exponential growth with respect to ...
