Realizing exceptional points of any order in the presence of symmetry

S Sayyad, FK Kunst - Physical Review Research, 2022 - APS
Exceptional points (EPs) appear as degeneracies in the spectrum of non-Hermitian matrices
at which the eigenvectors coalesce. In general, an EP of order n may find room to emerge if …
