Experimental observation of PT symmetry breaking near divergent exceptional points
M. Sakhdari, M. Hajizadegan, Q. Zhong +3
Standard exceptional points (EPs) are non-Hermitian degeneracies that occur in open systems. At an EP, the Taylor series expansion becomes singular and fails to converge -- a featu…

Superdirective Leaky Radiation from a PT-Synthetic Metachannel
Mehdi Hajizadegan, Pai-Yen Chen
Spectral singularities appearing in parity-time (PT)-symmetric non-Hermitian optical systems have aroused a growing interest due to their new, exhilarating applications, such as bi…
