Implementing non-Abelian Hatano-Nelson model in electric circuits
Xiangru Chen, Jien Wu, Xingyu Chen +6
Non-Hermitian systems generally host complex spectra that bring unique spectral topologies, leading to the spectral braiding and non-Hermitian skin effect. The experimental explora…
Higher-order exceptional ring semimetal with real hinge states in phononic crystals
Yejian Hu, Zhenhang Pu, Xiangru Chen +5
Non-Hermitian topological phase, with the novel concepts such as exceptional points and skin effect, has opened up a new paradigm beyond Hermitian topological physics. Exceptional…
Lossy phononic metamaterials for valley manipulation
Shunda Yin, Qiuyan Zhou, Yuxiang Xi +5
Non-Hermitian physics characterized by complex band spectra has established a new paradigm in condensed matter systems and metamaterials. Recently, non-Hermitian gain and nonrecipr…
Dimensional hierarchy of topological bound states in the continuum
Shunda Yin, Zhenyu Wang, Liping Ye +5
Bound states in the continuum (BICs), with the ability of trapping and manipulating waves within the radiation continuum, have gained significant attention for their potential appl…
