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…
Non-Hermitian exceptional physics in RP^2 hyperbolic media
Shengyu Hu, Zhiwei Guo, Wenwei Liu +2
Conventional momentum space provides an orientable base space of a torus for topological classifications based on band theory. Here, we introduce a non-orientable momentum space is…
Real-projective-plane hybrid-order topological insulator realized in phononic crystals
Pengtao Lai, Jien Wu, Zhenhang Pu +7
The manifold of the fundamental domain of the Brillouin zone is always considered to be a torus. However, under the synthetic gauge field, the Brillouin manifold can be modified by…
Acoustic topological Anderson insulators
Hui Liu, Boyang Xie, Haonan Wang +6
Recent breakthrough on topological Anderson insulators revealed the breakdown of the traditional perception that sufficiently strong disorder may induce the appearance of topologic…
