Abstract: Exceptional points (EPs), singularities in non-Hermitian systems where eigenvalues and eigenvectors coalesce, have enabled groundbreaking phenomena such as unidirectional invisibility, chiral transmission, and enhanced sensing. However, their sensitivity to perturbations, particularly frequency detuning, poses a… read more here.
