Observation of Erratic Non-Hermitian Skin Effect in Phononic Crystals

Yujian Yuan, Jie Liu, He Gao +3

The erratic non-Hermitian skin effect (ENHSE), emerging from the interplay between disorders and locally nonreciprocal yet globally reciprocal couplings, has reshaped the conventio…

Layer-number parity induced topological phase transition

Kai Chen, Junyan Guan, Jiamin Guo +3

We demonstrate that stacking topologically trivial layers, under enforced symmetry restrictions, yields emergent topological phases with protected boundary states. Remarkably, the…

Transient non-Hermitian skin effect

Zhongming Gu, He Gao, Haoran Xue +3

The discovery of non-Hermitian skin effect (NHSE) has opened an exciting direction for unveiling unusual physics and phenomena in non-Hermitian system. Despite notable theoretical…

Anomalous Floquet non-Hermitian skin effect in a ring resonator lattice

He Gao, Haoran Xue, Zhongming Gu +6

We present a one-dimensional coupled ring resonator lattice exhibiting a variant of the non- Hermitian skin effect (NHSE) that we call the anomalous Floquet NHSE. Unlike existing a…

Non-Hermitian route to higher-order topology in an acoustic crystal

He Gao, Haoran Xue, Zhongming Gu +3

Topological phases of matter are classified based on their Hermitian Hamiltonians, whose real-valued dispersions together with orthogonal eigenstates form nontrivial topology. In t…
