| 4 | Hybridization of different types of exceptional points显示文摘A large number of different types of second-order non-Hermitian degeneracies called exceptional points(EPs)were found in various physical systems depending on the mechanism of coupling between eigenstates.We show that these EPs can be hybridized to form higher-order EPs,which preserve the original properties of the initial EPs before hybridization.For a demonstration,we hybridize chiral and supermode second-order EPs,where the former and the latter are the results of intra-disk and inter-disk mode coupling in an optical system comprised of two Mie-scale microdisks and one Rayleigh-scale scatterer.The high sensitivity of the resulting third-order EP against external perturbations in our feasible system is emphasized. | JINHYEOK RYU SUNJAE GWAK JAEWON KIM HYEON-HYE YU JI-HWAN KIM JI-WON LEE CHANG-HWAN YI CHIL-MIN KIM | 2019 | Photonics Research2019，7，12： | 0 |
