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…
