Enhancement of signal-to-noise ratio at a high-order exceptional point of coherent perfect absorption

Zi-Qi Wang, Yi-Ming Sun, Yao-Dong Hu +4

Exceptional points (EPs) in non-Hermitian systems offer a remarkably strong response to weak perturbations, but the nonorthogonal nature of the corresponding eigenvectors causes no…

Unidirectional exceptional point of reflectionless states in a magnonic mirror array

Zi-Qi Wang, Yuan-Peng Peng, Yi-Pu Wang +1

Exceptional points (EPs) in non-Hermitian systems are singularities where both eigenvalues and eigenvectors coalesce. In scattering systems, EPs correspond to the merging of scatte…
