Multiplexed chiral and helical acoustic anomaly bulk states in an inverse-designed metamaterial
Xueyun Wen, Zhihao Lan, Zhongming Gu +2
Valley and pseudospin are fundamental degrees of freedom (DOFs) in topological acoustics. However, they have so far been realized mostly in separate systems. Here, we achieve the m…
Spin-Orbit Induced Confinement of Correlated Bound States in the Continuum
Kai Chen, Junyan Guan, Zhongming Gu +1
Repulsively bound doublons are two-particle composites formed by strong interactions and are usually separated from the scattering continuum. Introducing spin-orbit coupling fundam…
Spatiotemporal Vortex Rings Induced by Spatiotemporal Coupling
Zhiling Zhou, Wei Zhong, Tong Fu +4
Vortices and vortex rings are topological structures that arise in various physical systems. However, the generation of spatiotemporal vortices (STVs) and vortex rings (STVRs) has…
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…
Broadband non-reciprocal transmission of sound with invariant frequency
Zhong-ming Gu, Jie Hu, Bin Liang +2
The emergence of "acoustic diode" (AD) capable of rectifying acoustic wave like electrical diodes do to electricity has been believed to be able to offer unconventional manipulatio…
