Observation of exceptional topology and nonlocal skin effect in Klein bottle electric circuits
Pengtao Lai, Xiangru Chen, Yugan Tang +7
Symmetry and its representation play a crucial role in topological phases, including both Hermitian and non-Hermitian paradigms. In the presence of synthetic gauge field, spatial s…

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…
