PT-symmetric feedback induced linewidth narrowing
Yuanjiang Tang, Chao Liang, Xin Wen +3
Narrow linewidth is a long-pursuing goal in precision measurement and sensing. We propose a parity-time (PT )-symmetric feedback method to narrow the linewidths of resonance system…

Observation of Exceptional Points in Thermal Atomic Ensembles
Chao Liang, Yuanjiang Tang, An-Ning Xu +1
Exceptional points (EPs) in non-Hermitian systems have recently attracted wide interests and spawned intriguing prospects for enhanced sensing. However, EPs have not yet been reali…
