Loss-induced Floquet non-Hermitian skin effect
Yaohua Li, Cuicui Lu, Shuang Zhang +1
Non-Hermitian topological systems have attracted lots of interest due to their unique topological properties when the non-Hermitian skin effect (NHSE) appears. However, the experim…

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…
