Comment on "Symmetry Breaking and Laser-Absorber Modes in Optical Scattering Systems"

A. A. Zyablovsky, A. P. Vinogradov, A. V. Dorofeenko +2

We show that PT-symmetry may exist only for isolated frequencies in optical systems. Therefore, PT-symmetry breaking transitions as the frequency is tuned up, discussed in Y. D. Ch…
