Asymmetric lasing at spectral singularities
L. Jin
Scattering coefficients can diverge at spectral singularities. In such situation, the stationary solution becomes a laser solution with outgoing waves only. We explore a parity-tim…

Parity-time symmetric coupled asymmetric dimers
L. Jin
We investigate a parity-time (PT) symmetric system that consists of two symmetrically coupled asymmetric dimers. The enclosed magnetic flux controls the PT phase transition. The sy…

Sensitivity of parameter estimation near the exceptional point of a non-Hermitian system
Chong Chen, Liang Jin, Ren-Bao Liu
The exceptional points of non-Hermitian systems, where different energy eigenstates merge into an identical one, have many intriguing properties that have no counterparts in He…
