Temporal refraction and reflection in modulated mechanical metabeams: theory and physical observation
Shaoyun Wang, Nan Shao, Hui Chen +6
Wave reflection and refraction at a time interface follow different conservation laws compared to conventional scattering at a spatial interface. This study presents the experiment…
Smart patterning for topological pumping of elastic surface waves
Shaoyun Wang, Zhou Hu, Qian Wu +4
Topological pumping supplies a robust mechanism to steer waves across a sample without being affected by disorders and defects. For the first time, we demonstrate the pumping of el…
Physical rendering of synthetic spaces for topological sound transport
Hui Chen, Hongkuan Zhang, Qian Wu +5
Synthetic dimensions can be rendered in the physical space and this has been achieved with photonics and cold atomic gases, however, little to no work has been succeeded in acousti…
Channel-Coupling Fano Resonance and Acoustic Metadamping
Huy Nguyen, Qian Wu, Hui Chen +1
Fano resonance featuring asymmetric spectral profiles originates from the interference of local resonances and background continuum. Its narrow-band nature looks seemingly adverse…
Microtwist elasticity: A continuum approach to zero modes and topological polarization in Kagome lattices
Hussein Nassar, Hui Chen, Guoliang Huang
The topologically polarized isostatic lattices discovered by Kane and Lubensky (2014, Nat. Phys. 10, 39-45) challenged the standard effective medium theories used in the modeling o…
Elastic quantum spin-Hall effect in Kagome lattices
Hui Chen, Hussein Nassar, Andrew N. Norris +2
A Quantum Spin-Hall Insulator (QSHI) is implemented into a simple mass-spring Kagome lattice. The transition from the trivial state to the topological one is described by an invari…
